If you were Jack Dorsey, one of the co-founders and current chairman of Twitter, you'd want to think about something else big to follow up on your huge success.

While it doesn't sound like anything groundbreaking, Dorsey's new company Square is developing a tiny white cube (see photo above) that plugs into the headphone jack on either an iPhone or iPod touch. The cube is a credit card reader, something missing from all of those credit card apps currently in the iTunes App Store.

The Square iPhone Payment System consists of the reader and an app. After a card swipe, the customer uses a finger to sign the iPod touch or iPhone, one of the participants in the transaction enters the customer's email address, and a receipt with the location of the transaction, the signature, and other standard information is emailed to the customer.

While most online journalists are anticipating that this device and software are going to be used in retail (can you say Apple Store?), I think Dorsey has bigger ideas - let's face it, the guy doesn't think small. So why not make it possible for anyone with an iPhone or iPod touch to be able to accept credit cards for payments? Word has it that the card reader's manufacturing price will be as low as US$0.40, which means that Square could give away the readers and still make money on the transaction fees.

If the relationship between Apple and Mac CPU provider Intel was any closer, the two companies might have to start labeling their record collections and discussing whether to keep the wagon wheel table. In an intriguing technology demonstration last week, it was pointed out that the in-development Intel ultrafast optical connection called Light Peak was being shown on a rather elaborate hackintosh, running good old Mac OS X. This raised an eyebrow or two, but the background story seems to be just as interesting.

Engadget reports today, based on conversations with an 'extremely reliable source,' that Apple is behind the Light Peak technology, with C-suite-level discussions between the two companies dating back to 2007 about the specific implementation and capabilities of Light Peak. The post goes on to suggest that Apple will be doing rapid adoption of the optical tech a year from now, with Mac introductions slated for autumn of 2010 with the new port, and a low-powered version to follow along in the 2011 timeframe with future iPhones.

With the initial specification set to transfer data at a blistering 10Gpbs full duplex over cables as long as 100 meters (and with speeds up to 100Gbps lined up for future revisions), a single Light Peak connection could replace DVI, USB, gigabit Ethernet, FireWire, eSATA and just about anything else that would connect your computer to its environs.

One cable for everything, reducing clutter and increasing elegance? You have to admit, it does sound rather Jobsian.

With only a few hours more to wait until the packages start arriving and the stores start selling Snow Leopard, the reviews are beginning to pour in. To summarize: it's faster, it's (mostly) stable, yay new Finder, mostly yay new QuickTime (good thing you can still install the QuickTime 7 player), and in the words of our colleagues at Engadget: "Here's the thing about Snow Leopard, the single inescapable fact that hung over our heads as we ran our tests and took our screenshots and made our graphs: it's $30. $30!"

• Uncle Walt Mossberg at AllThingsD: "Overall, I believe Snow Leopard will help keep the Mac an appealing choice for computer buyers, and I can recommend it to existing Mac owners seeking more speed and disk space, or wanting to more easily use Exchange. But I don't consider Snow Leopard a must-have upgrade for average consumers. It's more of a nice-to-have upgrade. If you're happy with Leopard, there's no reason to rush out and get Snow Leopard."
• Gizmodo's Brian Lam: "Challenging 30 years of ever more bloated software tradition, the changes here are about becoming a more effective middleware between the media and the hardware, reducing friction while becoming more useful by, well, being lighter, less visible."
• Macworld's Jason Snell: "Failing a massive makeover, then, we've got to take joy in the little gifts that Snow Leopard gives us. And there are a lot of them. I'd like to pick my favorite, but the fact is, they're all small enough that I can't really choose one. But if I could gather up the whole lot of them in my arms, I'd give them a hug."
• Ed Baig at USA Today: "In my experience, Mac OS X was already a superior operating system to Windows. With Exchange and other technologies, Snow Leopard adds bite, especially for business. But as upgrades go, this one is relatively tame."
• Wired's Brian X. Chen: "This upgrade won't deliver any radical interface changes to blow you away (not that we would want it to), but the price is more than fair for the number of performance improvements Snow Leopard delivers."
• Jason Parker at CNET: "Overall, we think that Snow Leopard did almost everything Apple says it set out to do: it refined and enhanced Leopard to make it easier to use. Though the system performs well in everyday use, many of our tests indicate it is slightly slower than the older version of Leopard in more intensive application processes. Still, we highly recommend upgrading for all the new features and Microsoft Exchange support."
• David Pogue in the NYT: "[I]f you're already running Leopard, paying the $30 for Snow Leopard is a no-brainer. You'll feel the leap forward in speed polish, and you'll keep experiencing those "oh, that's nice" moments for weeks to come. If you're running something earlier, the decision isn't as clear cut; you'll have to pay $170 and get Snow Leopard with Apple's creative-software suites -- whether you want them or not. Either way, the big story here isn't really Snow Leopard. It's the radical concept of a software update that's smaller, faster and better -- instead of bigger, slower and more bloated. May the rest of the industry take the hint."
• ...and the aforementioned Engadget review, with lots of delightful videos (captured with QuickTime X's new screencasting feature).

If you've got Snow Leopard questions, we've got answers. Throw a comment in this post, send us a tweet over at the Ask TUAW account, or visit over on the Facebook page. We're also hoping to put together a late-night Friday liveblog to take live feedback from upgraders, and then we'll be live again Sunday night for the talkcast where it will be all Snow Leopard, all the time.

Blogger Darren Murph over at our sister blog Engadget has posted a hands-on review and detailed photo gallery for a new extended battery pack and case for the iPhone -- the mophie Juice Pack Air.

Billed as the world's lightest and thinnest extended battery pack for the iPhone, the Juice Pack Air will ship on Tuesday, April 21st, at a suggested retail price of US$79.95. It's available in the usual black and white iPhone colors, as well as purple for all of those Colorado Rockies fans out there.

The mophie Juice Pack Air (link to website) has achieved the Apple "Works with iPhone" certification, has a 1200 mAh Lithium Polymer battery to double your talk or play time, and even has an integrated 4-LED charge status indicator so you know when you're really going to lose all of your power.

Darren found that with the Juice Pack Air and iPhone mated, the total package is only .75" (19 mm) thick and adds just a tad more width and height. Whether or not that's worth it to you depends on just how much you use your iPhone.

Be sure to check out Darren's hands-on review and see if the Juice Pack Air is the battery for you!

Say, just for the sake of argument, that you're Psystar. You've been served by Apple for selling (they claim) illegal clones of their machines, and selling their OS (which you claim isn't even copyrighted) on illegitimate hardware. Sure, you've won a minor victory in the battle, but generally, the opinion is that you're a dead company walking -- when a company like Apple not only has it out for you but has pretty legit claims to back themselves up, you could be said to be in trouble. And so, what do you do?

Well if you are Psystar, you apparently release more computers. Determined to stick it to Apple as hard as they possibly can before they're legally wiped off the map, Psystar has announced the release of the Open(3), a desktop running OS X and packing up to a 2.53GHz Core2Quad Q8200 processor, up to 4GB of RAM and 1TB of storage, and all of the other usual options you'd want on a machine like this (6x Blu-ray burner, GeForce 9500GT). Technically, the box starts at $599, but as Engagdet notes, even if you max it out to around $2000, you're still paying less than an equivalent Mac Pro.

This is pretty much the computer retail equivalent of Bugs Bunny kissing the hunter. We can imagine Apple's lawyers steaming from the ears at this point -- here's hoping Psystar gets to have their fun while they can.

There's been some growling and teeth-baring between Apple and Palm lately, but Engadget wanted to know: does Apple really have a case against Palm for their patented technology? They put their (and our) legal correspondent, Nilay Patel, on the case, and in this long but very interesting analysis piece, he answers: probably.

But things, as usual, aren't that simple. Apple's patents don't just cover "multitouch" -- they cover very specific behaviors using the multitouch feature, and if Palm's Pre phone doesn't use those behaviors, there's no infringement. Of course, Patel is only going off of video of the Pre -- they don't have it in hand yet -- so things could change before the unit is released, but they do find significant evidence that Palm may have stepped on some lines it shouldn't have.

Then again, as Patel and patent attorney Mathew Gavronski discovered, Palm's got some tricks of their own -- they've got a whole slew of easily findable patents that the iPhone appears to infringe upon, including using an ambient light sensor to define brightness, looking up contacts just by using initials, and a number of other functions. Then again again, Apple's got pending patents in the fire that it can revise in case they think Palm is really trying to hone in on their business.

So bottom line, this could be really messy or it could be really simple, and Engadget concludes that the ball is in Apple's court -- if there's going to be a war, they say, the first shot will be from them. Personally, I think it's all corporate posturing -- as Patel points out, Palm has much less to lose, not having sold a single unit yet, and Apple is just making sure they know what's what. But there is a lot of money here, and if one side decides it'll cost less to go after the other, the fur could fly.

It's pretty wild to have seen the iControlPad go from idea to concept to production, and here's the final step straight from Engadget: video of the device working just as planned. ZodTTD is playing quake4iphone on it, and while the naysayers will probably still have some nays to say, I'm convinced. If Apple is as serious as it seems about turning the iPhone and the iPod touch into serious gaming devices, it would be worth selling something like this as an official accessory. It's fine and good to say that the multitouch screen works even for traditional controls, but so far, we haven't seen a developer that's been able to put "buttons" on the screen and still be able to make worthwhile use of screen space.

As Engadget says, there's still no price or release date on the iControlPad, and given that it's working on jailbroken games right now, there's no sign yet that we'll have any official App Store support. But it's an idea for which the time, in my humble opinion, has come.

On Friday, AppleInsider noted that Apple.pro, a hit-and-miss Chinese rumor blog, claims a 15-inch MacBook Air is on the way. The post in Chinese (and a copy run through Google Translate) is available.

The site claims the new Air will use low-voltage Intel Core 2 processors, and will be geared for "the older [with] poor eyesight."

AppleInsider includes a history of Apple.pro's predictions, and so far, they're batting .500. I'm not saying I'm any better (fact is, I haven't been to the batting cages in months), so take all this with a proverbial grain of salt.

If the rumors are true, it's unclear how utile a larger MacBook Air will be, especially if the key differentiating factor of the current Air is its size and weight. While it will have to be less hefty than, say, the 15-inch MacBook Pro, a larger MacBook Air seems like it's trying to fill a gap that doesn't exist: at the highest end of Apple's notebook pricing spectrum.

As for pricing (for the US, at least), perhaps we can speculate with an analogy: If a 2.4GHz MacBook is to a 2.4GHz 15-inch MacBook Pro, then a 1.86GHz MacBook Air is to a theoretical 1.86GHz 15-inch MacBook Air. Thus, $1,600 : $2,000 :: $2,500 : $3,125. Yikes: Even more expensive than the new 17-inch model ($2,800). Maybe the analogy isn't perfect, but that's still a pricey proposition to help those with "poor eyesight."

What do you think? Is there a market for a big, ultra-premium MacBook Air? Would you buy one? Sound off in comments.

Engadget is featuring an image allegedly showing details of Walmart's "soft launch" for the iPhone, scheduled to go on sale at 9 a.m. on December 28.

The note indicates that 488 Walmart stores were chosen for a "pilot" exercise, whereby each store will be given five iPhones to sell to Walmart employees between now and the 28th.

Associates will be able to purchase the phones for "full contract price and a two-year service agreement," but they can take advantage of a 15 percent discount on the contract as employees.

The purpose of the pilot program is to sort out any issues with the sales or activation process prior to the public launch date. If anything, it will make for a happy holiday for 2,440 Walmart associates.

Wired's Brian X. Chen writes that Apple will release a new version of the Mac mini at Macworld Expo early next month.

Chen's unnamed source didn't disclose any details about the Mac mini, but Chen offered plenty of specification speculation.

Based on "trends seen in Apple's latest products," Chen expects the new Mac mini to feature a unibody enclosure with speeds and video specs that closely match the new unibody MacBooks.

This follows another rumor of a budget-priced, small-form-factor iPhone that could be announced at the same time. Nilay Patel, of our sister blog Engadget, notes that this may be a reaction to slowing sales numbers, and an overall reticence by consumers to drop large amounts of money on a new computer system.

We'll see next month: The keynote presentation is scheduled for January 6. Macworld Expo typically announces by now if Steve Jobs will give the presentation, but they've been keeping mum about his involvement so far.

Our sister site Engadget notes that iDealsChina found this rendering of a silicone case for a new iPhone-like device with a smaller form factor.

iDealsChina says the case is "in production," and has many 3D images of a variety of angles. The device may be unveiled during Macworld Expo next month. The site also claims the "iPhone nano" will have three "sensors," a camera, a "mirror screen" and no 3G. The device will allegedly start production on December 20th at a rate of 60,000 to 80,000 units a day.

This falls in line with unsourced rumors of a wireless product slated for announcement at Macworld. It could wind up being the magic $99 Walmart iPhone that we've heard so much about.

The look of the new iPod nanos was leaked (famously by Kevin Rose) earlier this year as a result of a supplier showing off renderings of new cases for the device. According to iDealsChina, "...once one company starts making a mold their information is passed onto other mold companies or accessory companies through a China underground network."

Just in case you missed the Apple event today, they released some pretty neat upgrades to their notebook line, and a new 24" LED Cinema display. While we were not invited to the fun party, our sister blog, Engadget was -- and they took some awesome hands-on photos.

So far, they have played around with all of the products except the MacBook Air. You can see the hands-on pictures by clicking the links below:

• New MacBook Pros
• New MacBooks
  
• New Cinema Displays
  

You may have noticed from the pictures (i.e. the one above) that the new MacBooks/Pros only have glossy screens (and by glossy, we mean like a mirror). Apple tells me that the screens are in fact glass, and not a plastic overlay.

We want to know how you feel about Apple's move to all-glossy screens. Be sure to express your thoughts in the comments, and take part in our poll.

Our sister site Engadget reports that Apple is now offering unlocked iPhones in Hong Kong via its online store. HK$5,500 (≈ US$700) will buy you an 8GB model, HK$6,200 (≈ US$800) gets you 16GB.

The Apple Store's terms and conditions limit sales to individuals in Hong Kong only, but who knows what the gray market will bring.

Three Russian carriers will also begin selling unlocked iPhones on October 3, with the 8GB model selling for over US$900.

In related news, 29 new countries will begin selling the iPhone, some today: Botswana, Brazil, Cameroon, Central African Republic, Croatia, Dominican Republic, Egypt, Equatorial Guinea, Guinea, Guinea-Bissau, Ivory Coast, Jamaica, Jordan, Kenya, Latvia, Lithuania, Madagascar, Mali, Malta, Mauritius, Nicaragua, Niger, Panama, Qatar, Senegal, South Africa, Turkey and Venezuela.

Whoo baby, the rumors and pics just keep flowing out of the cyberwebs. Engadget has posted two blurry images since late last night. Not sketches or renderings or quiet whispers, but real photos. Or fake photos. Not like this type of fakery is hard. Still, all signs keep pointing to our beloved 3g nano going on a diet next Tuesday. Serious joggers everywhere may rejoice (personally I prefer the 2g form factor for running).

One more thing... iTunes 8 would be a logical announcement, and the rumors of a subscription model might make sense. We got a suggestion (not a tip, this was merely someone's idea) that Apple might give away some flavor of iPod with a 2-year committment to subscribers. I'm not sure the "act now and we'll throw in this handy shuffle!" angle is Apple's style, but it might be the sort of thing they'd do in a soft economy to keep people hooked on the iTunes/iPod ecosystem. Either way we'll know in a few days, won't we? And yes, TUAW will liveblog the September 9th event for your amusement and edification.

While the TUAW team was enjoying our holiday grilling (important safety tip: be sure to clean out the grease trap on your grill at the end of the season, so you don't have an incendiary problem... and also, it's true that baking soda really works well on grease fires) our sister scribes at Engadget were pumping out a few posts on some percolating iPhone & iPod items, mostly from the Berlin IFA trade show. The scorecard:

• The first wild sighting of a case for the rumored "skinny iPod nano" was picked up by Engadget Spanish and translated for English-speaking audiences. The Hama case even has a full gallery of photos over at ES. It's beginning to look like Kevin Rose (no relation!) may have been right about this one.
• The kitchen is rocking with the new "made for iPhone refrigerator" from Slovenian manufacturer Gorenje. That's the unit in the picture on the right. Aside from music and video playback, the iFridge features an iPhone-optimized web portal that lets you control your WiFi enabled appliances, Jetsons-style. I'm simultaneously amused, appalled, and seriously jonesing for a new refrigerator.

One rumor post that, while it still may pan out, is awaiting some evidentiary support: this Best Buy circular leak that purports to show a new iPod touch model. We all want a new touch, but in this case the circular turns out to be over a month old. Good thing I can still save that $300 and put it towards the iFridge
