I love my kindle
, but I'm not in nursing school
. From what I hear, it's not the best thing to read reference books on, and there are multiple apps to read your books with the ipad. The kindle has no page numbers since it fits the content to its screen, it has "location" numbers and I don't know how the heck you reference that when writing a bibliography. Maybe the MLA handbook writers have some homework to do, eh? If they do figure that little problem out, it would be great but I'm not holding my breath.
The kindle does come with wifi built in and you will get whatever speed the wifi around you has available up to 3G but it's the device itself that makes loading pages take a long time. And you only get static pages. So if you only want to look something up on wikipedia real quick and there is no other conceivable internet access, ok. Otherwise, uh no. When I was in school, like one teacher and one student had a pda at all, there were only a few people who ever used their cellphones for texting, etc. and yet the internet did come in real handy during homework and research, for clarifying and looking stuff up. (And this was 2003-2005, not too long ago.)
So if I were you - I'd look at an ipad or netbook-like thing for school. All I wanted was to read, read, read and I'm doing fine with my kindle, but you really need something that can help you out more and faster for school.
