It’s a Macworld...

...and we get to live in it. Apple unveiled the ultra-thin MacBook Air at San Francisco’s Moscone Center on Tuesday. Watch the keynote address here. (Or read Engadget’s live play-by-play.) New York Times’ columnist and CNBC contributor David Pogue sums up the major announcements here.

1) A one-terabyte, wireless back-up drive called Time Capsule that sells for $500
2) New software for the iPhone that pinpoints your location using cell towers and wireless hotspots
3) Movie rentals from iTunes for $4; movies last 24 hours but can be started on one platform – such as a laptop – paused and then picked up on another – such as an iPhone
4) A 23% price drop to $230 on Apple TV and software enhancements
5) the three-pound, super-slim $1800 MacBook Air

“One of the most significant things in this MacBook Air was that they’re introducing a lot of gesture-based user interface,” says Walter Mossberg of the Wall Street Journal.

“If you have a picture...you can do what they call pinching. You do it on the touch pad, not on the screen...That in some ways may end up being the biggest legacy,” Mossberg adds. ”All thin notebooks have compromises...It only has one way to get on the Internet – wirelessly. It doesn’t have an ethernet jack...Now that may be okay. Sometimes Apple moves ahead of the industry dropping features.”

The slenderella laptop won’t hit the stores for another two weeks. And Mossberg hasn’t taken the laptop for a test drive yet, so it’ll take a few weeks before he writes his first review. But the machine already has one grumbler. A hrrumph from Slate, natch. However, MacBook Air already has some third-party accessories, namely a vinyl laptop sleeve that looks just like an inter-office envelope.

Pogue further reports on the hypnotic charms of a Steve Jobs keynote here. (Sorry, the Grey Lady doesn’t do embedable video yet.) But somebody did catch Pogue’s, uh, cabaret act at Macworld, posted above. It’s one part Mark Russell, one part Roberta Flack and two parts Cupertino.

Meanwhile, Gizmodo wonders if design cues to future Apple products can be found in Braun electronics from the ’60s. In a side-by-side comparison of Apple and Braun products, Gizmodo proposes that past performance will predict future results. But one could also argue that Braun’s Dieter Rams and Apple’s Jonathan Ive just share a great eye for clean, simple design with a purpose, no matter the decade. However, everybody can get the signature Steve Jobs look here.
