Get an UltraBook, Save Your Back!
"The Ultrabook can basically be described as a Mac Book Air for the non-Apple user. However, the form factor does take a bit of getting used to."
Seems like more and more industry pundits are coming around to the UltraBook way of thinking. Rob Enderle often has his own spin on things, but his view here is pretty much spot-on (except, IMHO, his comment about Apple being design over function - my MacBook Air is pretty darned functional!). Anyway, unburdening a typical backpack can be an interesting process, lightening it with an UltraBook is an added plus. Rob does a quick review of three systems, from ASUS, Toshiba and Dell, and, of course has opinions on each one, but prefers the Dell XPS 13 in the final tally, and likes the lessened load on his back. I agree, and I've taken to using an older laptop now as my "desktop" computer, and carrying only a lighter system at other times.
