We've mentioned Dropzone before as a Friday Favorite, but I just happened across the app while I was trying to solve a problem.

I suspect many TUAW readers find themselves in the same situation that I am in: I use a desktop and a laptop. I often find myself wanting to move files between these two machines, so here's what I do: switch to Finder, click on the shared Mac I want, navigate to the folder I'm looking for, and then track down the file I want to copy there and drag it over. I could drag a folder from the other computer to my "Places" sidebar in Finder, but honestly, I just never do.

What I wanted was something quick and painless. I tried to whip something up using Automator and Folder Actions where it would copy/move files saved in one folder to the other machine, but even that would get messy. Most often I don't want to move the file, I just want to copy it. I could put the files in Dropbox, but some of these files are sizable (i.e. the 30+ MB iMovie update). To use Dropbox for this would take a long time.

Turns out that Dropzone offers the perfect solution: by enabling FTP on both Macs (System Preferences > Sharing > File Sharing, then click the "Options" button, and check the box "Share files and folders using FTP") I now have a drag & drop solution to copying files between computers. Simply drag the file to the Dropzone icon on the dock and then drop it onto one of the many "dropzones" which I have defined, and Dropzone does the rest. Two folders that I added almost immediately? The "Automatically Add to iTunes" folder in the iTunes folder and the Auto Import folder from inside my iPhoto Library (you will have to control-click your iPhoto library and choose "Show Package Contents" to find the "Auto Import" folder).

There are several plugins available to extend Dropzone to other services such as ImageShack, TwitPic, Flickr, and more. For Internet services, not only will the file get copied to where you want it to go, but the URL will be placed on the clipboard so you can paste the URL wherever you want it to go. I often FTP files to my website, and files Dropzone FTPs to a website can also support putting the URL on the clipboard.

There are several other nifty options, Dropzones for starting the screensaver, putting your Mac to sleep, or drag & drop printing a file to the default printer. You can also zip files (or zip and email them) and many other conveniences.

The biggest feature of all was one that I almost overlooked until I watched a screencast from macosxscreencasts.com about Dropzone. A built-in Dropzone called "Install Application" will allow you to drag a .dmg onto Dropzone and have the DMG mounted, the app installed to /Applications, the DMG moved to the recycle bin, and the app launched (it also works with applications which have been .zip'd instead of put into a disk image).

If you are anything like me, the "install a new app" process is several steps that you repeat a lot. Dropzone's handling of it is incredibly fast and works really well. If it opens a DMG it cannot handle (such as an installer), it will simply open the folder. Great, start stuff that saves you time and frustration. Remember how computers were supposed to make our lives easier? Dropzone does just that.

Upon learning that the Oxford English Dictionary was going to be released on CD-ROM for the Mac, I pre-ordered it from Amazon.com for $244 back in December (list price $295, currently $212). Due to Amazon's "pre-order price guarantee" the final price was just under $200. This should be considered a bargain.

The printed version of the two-volume Shorter Oxford English Dictionary sells for $350,The Compact Oxford English Dictionary "in slipcase with reading glass" sells for $400, and the 20 volume complete dictionary set sells for $995. Since I am-and hope to remain-married, I did not even consider spending $1000 on the complete 20 volume set (for very long). But a CD-ROM? That doesn't take up any space at all, and it's at a fraction of the price!

(I should probably note that Mac OS X comes with the "New Oxford American Dictionary" which is not the same thing as the OED, despite the similar sounding name.)

The CD-ROM lists itself as "version 4" but this is the first version to be "native" on the Mac. If there was a way to emphasize the quotation marks around the word "native" I would do so, because as I quickly learned, the OED puts the "ugly" in "butt ugly Windows port." The image you see above is the application icon. Have you ever seen an uglier icon? Have you ever seen an uglier icon for a $300 Mac application?

For the last couple of weeks, I've been testing the Verizon MiFi portable WiFi hotspot. After writing about the MiFi, a few months back, I was placed on a waiting list to receive a test unit. Could the MiFi enhance the iPod touch experience to bring it into the realm of the iPhone? A unit finally came free and I finally got my hands-on experience to discover whether my assumptions would be proved right or wrong.

The MiFi, which is a portable EV-DO router, provides a 3G connection through an absolutely tiny unit. All plastic, it's about as thick as an iPhone and about two-thirds as large as its front face. The MiFi's entire user interface is its single button (seen at the bottom right of the image here). When pressed, the button switches on and glows green. Pressed again and held, the unit turns off and the green glow disappears. Sprint offers a near-identical unit, except it's finished in brushed metal instead of black.

Read on to discover how my MiFi testing went...

Living in a multiple iPhone and iPod household is both fun and annoying.

It's fun to talk about cool apps and play multi-user games, but it's annoying trying to find a place to plug in our iPhones and iPods. Right now we have two iPhone 3GS's, an original iPhone being used as a game device, and an iPod nano that all need charging.

Things have been a lot easier in our household since we got a Dexim Dual Dock Charger. This unit, available for $44.95 from RichardSolo.com or directly from Dexim, is an attractive and functional dock in which you can simultaneously charge two iPhones, two iPods, or any combination imaginable. Since the devices need to be held securely in the dock, Dexim includes a set of plastic insert cradles that fit the bottom of your particular device (no, I'm not using them in the photo above). There are cradles for the iPhone 3G, iPhone 2G, iPod touch, iPod Classic, iPod nano, and 5G/U2 iPod.

When a device is placed in the dock for charging, a cool blue LED light goes on. That could be irritating if you want to use the Dual Dock Charger in a bedroom, so a switch to turn off the light is thoughtfully provided. We placed ours on a small table located on the way to our garage, so we can just pick up our phones on the way out of the house.

The Dexim Dual Dock Charger allows us to keep our iPhones constantly charged up, and it looks great while doing its job. We've had three-plus months of charging bliss without having to search for our cables, AC adapters, or iPhones. The original Apple chargers and cables are now used for topping off the devices when we're away from home, or for syncing with our Macs (the Dual Dock doesn't provide syncing capability).

If you live in a multi-iPhone family, the Dexim Dual Dock Charger is a must-have gadget.

Webcams are great, but when they're built into your display or laptop, they are usually good for only a couple of things -- video chats of your talking head or taking goofy pictures with Photo Booth. Ecamm, the development firm that makes the Call Recorder software we use to record the weekly TUAW Talkcast, demoed a tiny Bluetooth webcam at Macworld Expo in January. That webcam, the Ecamm BT-1, is now shipping and TUAW recently had an opportunity to test-drive one.

The US$149.00 BT-1 comes in a small box with a USB charging cable and one other useful accessory; a diminutive tripod to hold the webcam steady. The tripod is no slouch, as it has extendable legs and a tilt/pan head. For something that you can stick in your pocket, the BT-1 tripod is surprisingly sturdy.

Once charged, the BT-1 works for about 4 hours beaming 640 x 480 H.264-encoded video with stereo sound to your computer. Charging the BT-1 is as simple as plugging one end of the cable into a Mac's USB port or an iPhone charging brick, then plugging the other end into the BT-1's mini-USB port. While it's charging, a small LED glows, and when the BT-1 is fully charged the light goes off.

Like my colleague Mel Martin, I've had a serious GPS jones for quite a while. When I was in much better shape, I rode the local trails on a mountain bike with a Garmin eTrex Summit. It didn't have any maps, nor did I really need any for what I was doing. My next GPS receiver was a Garmin GPSmap 60cs that I used for geocaching. It had a nice color screen and some limited maps, but really didn't do a very good job of helping me find my way around town.

The third GPS unit was another Garmin, and in this case it was my first real "navigator." I still have it; it's the Garmin nüvi 660, which is an awesome little unit that can help you find your way around the US or Europe (depending on the model you purchase), act as an MP3 player, or even work as a fairly serviceable hands-free unit for Bluetooth phones. I've used mine with my iPhones since way back in 2007, and have enjoyed hearing the amplified voices of callers blasting out of the nüvi.

It's best capability, of course, is as a navigator. In this post, I'm going to compare the AT&T Navigator app [App Store] and service with the nüvi, and give you my take on how this free app works. Mel already filled you in on some of the details in his earlier post; we agreed that I'd give you the road test perspective.

iPhone 3G and 3G S owners now have an attractive, lightweight, and functional way to provide extra juice to their power-hungry devices -- the Mophie Juice Pack Air. Available in black, white, and purple, the Juice Pack Air is a slightly more svelte version of Mophie's Juice Pack. Compared to the original Juice Pack, the Juice Pack Air is .1" (2.54 mm) thinner and a full third of an ounce (9.44 grams) lighter.

I had a chance to try out the Juice Pack Air, and my impressions are quite positive, albeit with one exception. Read on for a TUAW road test of Mophie's latest battery pack.

There are few times I have used software that really caused my jaw to drop. Photomatix Pro did just that. It's a Mac OS X utility that allows you to create what are called High Dynamic Range (HDR) images from separate digital exposures taken at different shutter speeds (exposure levels). These pictures are far more colorful and impressive in their tonal range and saturation.

Many digital cameras have something called AEB, or Automatic Exposure Bracketing. You click the shutter once, and the camera takes 3 pictures instead of just one. In my case I usually shoot a normally exposed image, then one 2 stops under, and another one 2 stops over. If your camera doesn't have AEB you can do this manually.

Photomatix Pro combines the three exposures you've taken into one, and tone maps the image into a JPEG or TIFF that displays a really wide dynamic range. The result is often a stunning picture, with little loss in the shadowy areas, and no blown-out highlights. It's hard to do if you are shooting people because they will move between the 3 exposures, but works great with landscapes. A tripod is recommended, but I've done just fine handheld and Photomatix Pro will automatically line up (register) the 3 images.

Words can't describe the difference, so I've included a few examples to look at. There are other Mac apps that do similar things, but I've had the best luck with Photomatix Pro. They also make a Photoshop plug-in and one for Aperture, but I think the full program is the best. Newer versions of Photoshop also support the creation of these HDR images, but the results are not as spectacular in my view. There is also a free, basic version of the program that lets you combine 2 images, but it is simply not as effective.

You can search for a lot of information on HDR photography on the web. I have found this site to be very good, and it reviews the different software that is available. It's very easy to overdo the look of HDR images, and Photomatix Pro gives you lots of control. You can make your images really good, or outlandish. The control is in the hands of the photographer. To many, HDR will be old hat, but a lot of photographers haven't tried it, and will be pleasantly shocked at the results.

Since you can download Photomatix Pro for free, if you are serious about digital imaging, I'd give it a tryout. If you buy the full version it is US$99.00.

Here are some examples of how HDR imaging works. Of course these images are reduced in quality and resolution, so they only hint at the differences.

After I traveled to Africa in February with a Tom Bihn Western Flyer bag loaded with geek gear, I wrote a post talking about how I packed that bag for the trip. It was the perfect bag on that vacation, as it allowed me to pack all of my gear into various little nooks and crannies, and it converted to a backpack for easy lugging through airports. However, it wasn't the best bag for my many business trips in the USA.

Happy with the products that Tom Bihn makes, I decided to get their Checkpoint Flyer briefcase for my business travel. What makes this bag so special is that it is specially designed to take advantage of Transportation Security Administration (TSA) rules that allow you to keep a laptop inside a case as it's going through the x-ray machine, provided that case contains nothing else. That, of course, can be a huge problem if you're carrying backup drives, cables, backup cell phones, an Amazon Kindle 2, and other digital effluvia.

A tweet this afternoon pointed me to a post by Dave "MacSparky" Sparks titled The Netbook Experiment, in which he talked about his disappointment with a Dell mini 9 netbook. Since I was about to send out a tweet to the world at large announcing the sale of my Dell mini 9, I found it fascinating that Sparks had a similar experience to mine.

I wrote about creating a hackintosh (AKA hackb00k) out of a Dell mini 9 in a long post back in October of 2008, and at that time I was fairly impressed with the low cost and capabilities of the device. However, after actually using the mini 9 for six months, I find it almost useless as a "real computer" and have decided that it needs to go. The moral of the story? You definitely get what you pay for, and a $499 computer is not going to be a productivity tool. Even if you delude yourself into thinking that since you're only going to use it for email it will be a worthwhile investment, you're wrong. If you want to know how I came to these conclusions, read on.

I bought my 4GB iPhone way back on June 29th, 2007, release day for the US. Upon removing it from its box, all shiny and smooth, I thought, "I need a case for this thing." I'm what you call scratch-phobic. But then I saw the rigorous torture test that PCWorld subjected their unit to, and was persuaded to go commando.

Here it is nearly two years later and my iPhone's display still looks great. There's a single nick next to the earpiece but other than that it looks fantastic. The back is another story.

I have two kids aged 4 years and 6 years. Occasionally, I'll hand over the iPhone to keep them entertained. For instance, at the end of a day of boring errands when their patience is at an end, I'll whip out a little Wheels On The Bus [App Store link] or Pocket God. As any parent of young kids will tell you, one of the things they love to do is drop stuff.

My iPhone has seen the floor of the mall, Dunkin Donuts and my Saturn Vue. It's been in sand and sun. In other words, it needs protection. I picked up an Otterbox.

USB flash drives are a dime a dozen. They've gone from being a "wow" item a few years ago to a throwaway handout item. Many are cheap plastic devices that either come with a neck lanyard attached or with a small loop for attaching to a key ring. More often than not, they end up falling to pieces or getting lost.
The new LaCie iamaKey (highlighted above) is a USB 2.0 flash drive you'll actually use. Rather than being made out of plastic, it's made of solid metal. Rather than having a useless lanyard attached, there's a hole in the metal so you can put it on a key ring. It's about the size and shape of a key, so it's not out of place on a key ring.

iamaKey came with a tiny plastic cap that covered the connector. Of course, after about 15 minutes the cap disappeared. I was concerned about that until finding out that iamaKey uses a gold SIP connector that resists scratches and water. You don't need the cap at all.

So, does it still work after almost two months of riding around in a pocket with a bunch of other keys and change? Absolutely! It's been dropped multiple times, it's gotten soaked in the pocket of a pair of jeans I was wearing during a sudden downpour, and it's put up with winter cold while I've been out walking. iamaKey is rugged and fast, with up to 30 MB/s read rates and 10 MB/s write speeds.

iamaKey comes in 4 GB (US$19.99) and 8 GB (US$29.99) flavors. LaCie also sells the less rugged and larger itsaKey, which retails for US$3 less than iamaKey.

During the discussion earlier in the year about why Apple was blocking turn-by-turn GPS navigation apps for the iPhone 3G (it will be "legal" in iPhone 3.0), a reader pointed out that there have been a pair of turn-by-turn navigators in the App Store for quite a while.

Upon following the reader hint, I was surprised to find that XRoad G-Map US West (click opens iTunes) and East have the United States covered for navigation. These apps, US$24.99 each, don't have the voice prompts that most of us appreciate, but they do provide surprisingly accurate directions and a 3D navigation view that rivals the more expensive Garmin, TomTom, and Magellan dedicated navigators.

European and Canadian versions of the app are expected to be released by the end of this quarter, while Central / South America and Asian versions should arrive by the end of 2009.

Since I am the resident GPS geek at TUAW, I decided to give XRoad G-Map US West v1.3 a test drive and see how it performed compared to my Garmin nüvi navigator. While the XRoad product has some shortcomings, it's still worthy of a look if you're thinking about purchasing a navigation app. Click Read More to see how G-Map worked...or didn't.

Thinking green? Voltaic Systems' Generator laptop bag (US$499) might be just the thing to buy for Earth Day on April 22nd.
I had a chance to road test one of these incredibly cool bags for a month and was very impressed. What makes it so special? Well, it could be the big photovoltaic panel on one side of the Generator that provides 15 watts of power to feed your electronic devices. Voltaic points out that the Generator is the "first solar bag powerful enough to recharge a laptop." That panel charges an internal 58Wh Lithium Ion battery pack that can run most laptops.

The solar panel isn't the only thing that's green about this bag. The materials that make up the majority of the bag are made from recycled PET soda bottles. In fact, the shell, webbing, mesh and lining of the case are made of 100% recycled materials.

As promised, we're launching a new series called Road Tested where we try out various products for a month or more, see how they hold up to extended "real world" use, and report back our findings. To kick things off we're looking at the EcoRunner from Marware [thanks to our friends at Dr. Bott for the review unit].

The EcoRunner is a "green" product in that the primary material is not neoprene, but "a revolutionary environmentally friendly material." I'm not sure what that is, but I can say I like it better than neoprene -- it feels just as soft, but the cells are smaller and thus the material is more supple. The EcoRunner can be worn on the wrist or arm (using an extender strap, included) and is designed for the 4th-gen iPod nano. There's the requisite vinyl window for controlling playback and viewing the screen, plus the case can be used with the Nike+ Sport kit attached (there's a strap to keep everything in).

Does it work? Well, there's one caveat to our test: we used a 1st-gen nano, the white model that was infamous for being easily scratched. It's increasingly tough to find cases for this model, but we found the EcoRunner is stretchy enough to accommodate the slightly thicker model. The side effect of this, possibly due to thickness or the more squarish design: the vinyl window busted (see gallery), leaving the unit exposed and capable of falling out. Call it a "stress test." It's definitely a design challenge to secure the vinyl in a way that won't get too stressed, especially in cases where everything else is so stretchy.

The softness of the case can't be understated. It is really smooth and lightweight and stretchy. I'm partial to wrist straps, because I tend to skip around my playlists depending on my workout. If you find yourself monkeying with your nano during a workout, this is a terrific wrist strap. The extension strap to use it on your arm adds virtually no weight, and holds up well, but bulging biceps might strain that window. The Velcro used is very high quality, but the stitching on the end can sometimes be a little tricky to thread through the grommet -- so I recommend not removing it entirely. Just pull it off your wrist. One upside is that you can charge the nano in the case, so the entire unit becomes home to your nano. If you only use your nano for working out, you'll never have to remove it from the case.

After a month (OK, nearly 2 months) of solid use -- we're talking about near-daily use on the treadmill and at the gym -- the EcoRunner holds up well. As I said, using a 1st-gen nano isn't recommended by us or the manufacturer, so I don't know if the thinner nanos would bust the window after prolonged use. Other than that, there's very little visible wear-and-tear, and I'd recommend this especially if you a) prefer your nano on your wrist, and b) need a case that'll hold the Nike+ Sport kit. Your choices are pretty limited when it comes to both of those criteria, but the EcoRunner is a good bet either way. If you've had experience with this particular model, let us know in the comments.

UPDATE: Great questions in the comments! As far as sweat retention, since my wrist doesn't sweat too much, I'd have to say no problems there. You might have an issue with a very sweaty bicep, but I feel the material's tighter cells (as opposed the larger, more open cells found in neoprene) would guard pretty well against this. There's no signs of staining, either.

The extender strap adds a little over 6 inches to the overall strap length. Total that's 11.5 inches (see added gallery image). My puny biceps fit fine, but if you have some massive guns then yeah, you might have a problem.
