I'm far from a techie however this sounds tantamount to being a calculated chess move to crucify the competition (hello Adobe!) Gawker's article here "The Dark Side of Steve Jobs". As I've been travelling lately I've been struck by the sheer media machine that is Apple. Expect to see uber cool ads with celebrities and rockin' pop music. I tested it a bit, but frankly I think it weighs too much, and honestly has to be a target for theft. Most of the population is more likely to watch videos, create and edit youtube pieces and surf the net tending to their Twitter/Facebook accounts.
I'll give a few years before it become paperlite and cheaper? I wish, not for Canucks. Your wallet will drain faster than the battery.
