I've been looking at the Sony reader. I have been reading about the Nook. The Nook looks really cool. I can totally see carting one of those around on a business trip vs. a book. I guess obsolesence would be a worry. I imagine all those albums that folks bought on 8-track tape have to be bought again in some other format. Such is the nature of changing technology. Nothing to get out of date about a book. Books are wonderful. I think an e-reader would be a great alternative (kind of like cars and bikes are alternatives to each other, but neither will necessarily replace the other. Hmmmm).
