I apparently can’t follow my own advice: I recently purchased an ASUS Zenbook, one of a handful of first-generation Ultrabooks currently in the market and the one, I think, that most closely resembles Apple’s MacBook Air. And while I’m very enthusiastic about the Ultrabook form factor overall, I’m not sure I can recommend this particular rendition, at least not universally.
