MacBook Air is Apple's latest innovation. It is less than an inch thick and features a 13 inch screen and full back lit keyboard. I'm not usually big on superlative marketing, but this is the thinest notebook around. It doesn't have an optical drive, which is why it is so thin. Apple compensated for the lack of optical drive by allowing you to create a wireless connection to another computers drive to load software. It's pretty cool. I really like that they went beyond the superlatives and added some cool thinking into the product. I've seen plenty of products try to be the thinest, flattest, or fastest. None of these things mean much without a little consumer friendly design and innovation to match.
