Nope, the latest one. Against print, it's a wash for going sequentially from one page to the next.. but I also need to flick through many pages a second to scan or just get a feel for a book, and 1 page per second or two doesn't provide that.

I also frequently have multiple books open and jump between them scanning a lot as I do a lot of research. Again, not ideal for things like the Kindle, alas. But that's why I think we need both e-books and print.
