We're not sure what someone has been putting in the water lately, but two separate vendors pinged us with case giveaways within minutes of each other. They're both using Twitter as the entry mechanism for the giveaways.

The first giveaway is from our buddies at Evernote, who want you to win one of ten Griffin Clarifi iPhone 3G cases every Friday in March. The Clarifi is pretty sweet, with a built-in closeup lens for taking snaps that are perfect for Evernote.To enter, all you need to do is send a Twitter message containing the #EvernoteClarifiGiveaway hash tag.

Not to be out-cased, RadTech is doing a giveaway of 5 NeoCases. These are sweet form-fitting sleeve cases for MacBooks, iBooks, and PowerBooks. How do you enter? Tweet @radtech with a clever statement including the word "Neocase", and you're entered. The drawing will be held Monday, March 9, 2008, and you'll be able to choose the size of NeoCase for your favorite Mac notebook.

What are you waiting for? Get tweeting and win a case!

When researching this week's Ask TUAW I ran across a nifty little utility for reclaiming the function keys on a Mac portable or recent Apple external keyboard. Basically, FunctionFlip allows you to set the individual function keys to be regular F-keys instead of those special control keys (brightness, volume, iTunes, etc.).

While the Keyboard Preference Pane will let you flip all of the keys one way or the other, FunctionFlip lets you individually choose which ones you want. That way you can preserve whichever of the control functions you like, but regain access to certain of the F-keys without having to hold down the fn key. It can be a handy way to have your cake and eat it too.

FunctionFlip is a free download (donations requested) from Kevin Gessner.

Ars Technica reports that Apple will announce the latest additions to its list of vintage and obsolete machines on March 17. The list, initially reported through MacMerc, includes the following:

The "vintage" machines are ones where service parts are available to repair machines purchased in California due to existing statutes. This classification does not apply in the other 49 states.

• Xserve RAID
• Xserve (Slot Load)
• Xserve (Cluster Node)

The rest of the additions, to grace the "obsolete" list, include:

• PowerBook G4
• Power Mac G4 (Digital Audio)
• Power Mac G4 (Quicksilver)
• Macintosh Server G4 (Digital Audio)
• Macintosh Server G4 (Quicksilver)

These machines have all had good runs. I had a Quicksilver as my first post-college work computer and thought it was the greatest computer I've ever worked on the time - way, way back in the golden days of years gone by (aka 2002). These computers will now join their brethren in the Mac retirement home. But just because Apple classifies them as obsolete doesn't mean that you can't breathe new life into them.

Have fond memories of these machines? Share them in the comments!

MacMod.com has announced their honorees for the best mods on Macs that they saw last year, and you can see all of the hacks and mods over at their site right now. Most of the mods are case modifications, like the very slick iPhone custom, and the "Xbox G4," as seen above, which is a Powerbook G4 modded into the case of an Xbox 360 (with working ring of light!).

I find it interesting that despite all of the slick case designs and gadget melds, the winner ends up being a software hack (well, it's actually more than a software hack, but still, you won't find any neon tubing in this mod, just a beige case): Leopard running on a PowerMac 8500. The mod itself ends up being a fine trip over the history of Apple's current software, its past machines, and all of the gooey chips and hardware inside. Very cool. Kudos to all the modders for their work -- we can't wait to see what 2009 brings to the mod community.

I am a huge fan of Gelaskins, and my iPhone has boasted one since I discovered a display at a small Toronto store back in May. Adhesive art for your iPhone, iPod, and Mac is a fantastic concept and a great way to express yourself beyond the typical hardware case.

Infectious is another site that offers art for laptops, cars, and more. They have recently launched a line for the iPhone. The site currently has 38 different pieces of art for the iPhone, and is currently on sale for $9.99. The Infectious stickers will fit both generations of iPhones.

You will get a large piece of art for the back of the phone, and a smaller one for the front that goes over the Home button. The artwork for the front of the iPhone is a fantastic feature that Gelaskins doesn't have, and one that I find very attractive. It makes it easy to spot your phone without having to flip it over to check the back or activate the screen to check the wallpaper.

Art for laptops is starts at $29.99 and will fit the Powerbook G4, iBook, MacBook, MacBook Pro and MacBook Air. The artwork is made on 3M vinyl material and can be easily removed to put on another piece.

Infectious is currently offering a deal for TUAW readers. Use discount code TuawRocks for 10% off from now until December 31.

Like virtually all mobile computer manufacturers, Apple recommends that users calibrate their laptop batteries every few months, as Scott pointed out a couple of years ago. Unlike many manufacturers, however, Apple does not include a utility to automatically perform a calibration. Given Apple's uncanny ability to make things user-friendly, this seems like a bit of a glaring oversight.

What are the benefits of calibration? Primarily the goal is to ensure that the microprocessor in your battery provides an accurate estimate of how much time you have left on the battery. Over time it can lose track of just how much juice your battery has in it, and calibration gives it a very accurate reading on the battery's health.

Older battery technologies also benefited from a process called conditioning, which was typically performed the same way as a current battery's calibration process. In a nutshell, you fully charge the battery, fully discharge it, then fully charge it again. It's unclear whether modern lithium batteries gain anything in an actual capacity perspective from this process, or if it is simply a calibration of the microprocessor for the purpose of providing accurate time estimates.

Up until a few years ago, I had a 12" PowerBook G4 that I absolutely loved. It was truly portable (although the screen was a bit on the small side for me), relatively fast, and lightweight. Many of my consulting clients have asked if Apple had plans to replace the 12" PowerBook with a MacBook or MacBook Pro in the same form factor, but I've pointed them towards the 13" MacBook or MacBook Air instead.

There's still a vocal group of former PowerBook G4 users who would like to see Apple come out with a new MacBook Pro -- complete with SuperDrive, Intel Core 2 Duo processor, and Multi-Touch trackpad -- in that tiny 12" PowerBook case. If you're in their camp, visit and participate in the MBP12.com forum and add your voice to the people clamoring for a small, powerful MacBook Pro.

Do you think a 12" MacBook Pro would be a winner in the market? Take our poll!

Dear Santa Steve,

As my most recent bank statements show: I've most certainly not misbehaved over the course of this last year. I've queued for hours in the bitter cold, and sacrificed myself endured keyhole surgery for injuries from doing so - no really, that bit isn't hyperbole. If there's anyone who's been an exceptionally well behaved Apple fan, you've got to admit I'm up there with the best of them. So what on earth could I be asking for? Just a few simple things:

13" MacBook Pro / MacBook nano Steve, I can wax lyrical about the sheer brute force of my 17" MacBook Pro - I love it, I really do. But lugging it on the train for a ninety-minute commute everyday isn't the pleasurable workout you might expect. In fact, I'd quite like a little version of my MBP, so that I pack it into a reasonably-sized Crumpler with my Nikon D80 and not resort to hiring sherpas buying a small trolley-case to travel. So what might I be asking for? If you were to start by making the display 13 (matte) inches or there abouts, and keep a dedicated GPU, that'd be ace - a machine Aperture would love. In fact, you could even remove the optical drive from the body, and use SSD if you really, really, wanted. I can hear Jonny Ive say 'SSD may be a little way-off yet' in the background, but you get the idea? All I'm asking for is a modern-day 12" PowerBook. I've sold my soul to Cupertino maximised my overdraft told the bank not to block large charges from my local Apple Store, and you've got my bank details. So let's work something out, for I can't be the only one asking for such a machine this year.

Stability in my iPhone This one's arguably simpler Steve, what with it not requiring you to design any new hardware. I'd like my iPhone's iPod and Safari applications to get on better than you and John Sculley. I'm sorry, that was perhaps a little too forceful but I think I made my point. A software update to the device that brings some new functionality would be most welcome too, what with it being 'all about the software' and the SDK on the horizon.

Aperture 2 This one may seem out of place for Stevemas - for general wisdom places Macworld as the launch of more consumer-orientated products - so I'll happily be told 'be patient, my child' for this one. But with Aperture now the last of your professional applications not to see a notable (paid) update, I'm hopeful that whatever may be in the works arrives sooner rather than later.

There's but one more thing, and I'll be content for a while Steve. In fact, if there's one thing I'd choose from my requests this year, it would be this.... Let's take these big-media names to task, and encourage investment in, not criminalisation of, those who do buy their content online. Towards the end of 2007, Apple seemed to lose their iTunes momentum despite the year getting off to a good start. EMI went on the offensive, trying to capture hearts and minds by dropping DRM from their download sales. But since then, we've seen little continuation in the dream of eradicating DRM from our digital lifestyles. Steve, in 2008, all I want is for Apple to help bring the media industry back to serving the needs of its customers as a business model. Let's make it less of the iTunes Extortion and Shakedown Store, and all about the music once more.

There's cookies by the side of the MacBook Pro - and green tea simmering on it. Enjoy.

I'm definitely a big fan of iSlayer's iStat Pro widget. Whenever my older Powerbook acts a little weird, I can just pull up the Dashboard and tell at a glance what's going wrong ("Oh my, the CPU is running at 150 degrees again. Time to quit a few apps"). Now they've sent word that iStat menus, an even bigger and better stats program available to sit on the menubar, has hit version 1.2.

New to this version is process monitoring, better temperature and fan support in G4 Powerbooks (like mine), and a disk activity graph that let's you monitor disk performance over time. For keeping an eye on what's happening under your Mac's hood, there's almost nothing better, and all the iStat stuff is free.

Of course, if you do use one of their apps, make sure to send them some cash to help them keep up the good work. Always support good software, people. Just like NPR, if you don't support it, you'll lose it.

If it bleeds, it leads. If it goes boom, there's room. Fire inspires and there's no shame in flame.

What's the opposite of flamebait? It's when your PowerBook really does catch fire and nearly kills you--and you write a love letter like Jimm Lasser did. After his PowerBook burst into flames, he didn't lash out at Apple. He grew to love them even more. He writes, "a Mac almost killed me, and I came out of the whole experience feeling more strongly about Apple as a company." TUAW rejoices that Lasser survived and has been able to move on from the whole experience, but reiterates that this kind of bonding, consumer-trust-enhancing experience is not typical.

TUAW reader and Flickr user sninesix posted this snapshot of the USB CPU fan he rigged up to cool his PowerBook. When the original fan died, sninesix found an old fan he had lying around, removed the wires and hacked a USB cable onto it.

He then removed laptop's keyboard and positioned the fan just above the CPU. With a USB keyboard connected, he was back in business. Well done! You can watch a video explanation here.

If you'd like to see your own rig featured here, simply upload photos into our group Flickr pool. Each Sunday we'll comb through the most recent entries and declare a "Rig of the Week!"

TUAW reader Dylan O'Donnell has set up his Macbook Pro to snap a picture using the built-in iSight whenever its lid opens. He put together a simple command line capture utility and triggered it with Bernard Bahr's SleepWatcher. Then he added automatic uploads via FTP and displayed the results with the open source BolGallery.

"I initially did this as an anti-theft measure as the script will upload the photos to any FTP site for you, and the PHP gallery will autothumb and display the photos. Apart from the nauseating effect of seeing my ugly mug repeating, the result is good and I hope to maybe do a time lapse in quicktime sometime down the track!"

It's a cute idea, completely open source, and an excellent example of ingenuity in action. It's also a good example of the completely self-conscious reasons that I do not personally own a webcam. Me, in the morning, before I've woken up and had my caffeine? Not a pretty picture.

It hasn't been a really good year battery-wise. Battery defects made the news with overheating and spontaneous combustion. Today, Matsushita Electric Industrial Co. said it will begin mass producing a new and improved lithium-ion battery, one that presumably will not melt your PowerBook. Good news for consumers, even at the slightly higher prices anticipated for the more advanced technology. This DFW article does not reveal exactly how the new batteries will be changed in order to minimize the risk of spontaneous combustion, but "not bursting into flames" would be a good start.

Making your own laptop stand out of Legos is cool and all, but not all of us have kids of our own to steal toys from. So we turn to more accessible materials like wood. That's what Erik did. Using wood, lacquer and some copper wire, Erik created his own very elegant iCurve knockoff: The WoodStand. He shared it with us, so we're sharing it with you. Nice work, Erik!

Enjoy the pics - and if you make your own, tell us about it!
