The new MacBook Air announced at yesterday's Macworld keynote doesn't disappoint; it's pretty much the laptop I've wanted ever since I stupidly broke my 12" Powerbook trying to replace the hard drive. All things remaining the same, I'd buy it simply for the difference in weight, a full two pounds less than a MacBook. As someone who's put a lot of miles on his kicks with a laptop bag on his shoulder, that would make a world of difference.

What's interesting though, is what the MacBook Air isn't: it's not simply a sexier MacBook Pro on Jenny Craig, it's a different class of machine. John Gruber rightly points out that it's clearly designed as a secondary machine for people who do their heavy lifting on a desktop. Without another machine standing by at home or the office, only a select group of geeks could really get by without an optical drive, not to mention the diminished overall specs of the MacBook Air may not please a power user without reinforcements (a.k.a., the folks willing to spend upwards of $2000 on a laptop).
