I'm thinking about a tablet to help me with my Open University courses. Nowadays the OU provides its materials in downloadable format as well as in book form and there's also a lot of stuff on the website. It would be useful to be able to carry this stuff about with me without having to lug the books or a laptop. (I have a bad back and carrying even quite light loads is very tiring.) So I thought a tablet might be the answer.
It would need to have a very good screen as I would be reading an awful lot and it would need to have the facility to add a keyboard so that I could make notes. Obviously I'd like something with good all-round facilities too.
Any advice would be gratefully received.
