Interesting. I think I'd miss the smell and feel of an actual book, though.(does that make me weird? Yeh... maybe) I don't think I'd go out of my way to buy one, but I wouldn't be upset if I happened to get one as a gift.
Looks nice, but i'm not sure i'd like that rather than a book. Plus isn't reading a screen for a long period of time much worse for your eyes than reading a book for a long period of time?
Well, when I was younger, I needed to get glasses after a long bout of book reading. So I would surmise there's not much of a difference. I'd actually prefer this to a book because it can hold more than one book yet still feel like I am carrying one book.
