I'm getting a 12-inch PowerBook as a Christmas present, probably a discounted one with SuperDrive and 512RAM for $1470 at the campus bookstore. I know updates might happen, but so be it. My question is if there are any updated reviews, as of the last revision (around April I think)? I have seen just one or two of them, but I'm looking for more. Or if you could answer my question, how's the battery life specifically on the 12-inch PB? The iBook might be a better value, but again, this is a gift so I just pick one laptop around $1500. I'm a student and needed something light, so how's this?
