content: As far as I know, yes and yes. You'd have to convert your ebooks from whatever format their in (like epub) to mobi, using something like calibre though. I have a kindle 3 (I think, it's one of the older non-touch versions), and that doesn't really handle pdf files very well, if at all (can't remember if I've ever had to use it to read pdfs on though). This has probably been improved with newer versions, although I have no idea to what extent this is true. edit: spelling
