As much as I like the idea of a MacBook Air, the fact that my part-time job is classical CD critic means I need a computer that can play compact discs. That's how they come in the mail and I need a computer that can play 'em.
Also, $1000 for a laptop... gack!
Despite its awkwardness, and the fact that 3G costs so much per month, the iPad is more tempting to me.
