Still loving the kindle app for my phone - I can take my books (all three of them) anywhere and if I have a spare couple of minutes, I can catch up on some reading. I like that it synchs back to my PC over the aether, and that amazon will happily send you sample chapters of books for free.
Currently reading 'The City and The City', by China Mieville. Annoyingly the free sample finished just as it was getting interesting, which I guess is the point.
Still think ebooks should be significantly cheaper than actual paper, rather than just a bit cheaper.
