If I wanted something like that, Yvan, I'd have bought a Tablet PC

. I don't want something "A4" sized or larger; for me the Reader is the perfect size.
This really isn't a "one size fits all" market. There's room in the market for both "paperback book" sized devices like the Reader, and A4 sized devices such as your picture for technical manuals, newspapers, etc. Wouldn't you agree?
