Having had 100s of my books ruined by a recent flood at my home, I am thinking of spending some of the insurance money on a kindle instead. I would like something on to which I can download, read & annotate research papers - a search on google suggests that I need a dx. Has anyone got a kindle dx and can you buy them in the UK? Unless I'm being very stupid (which is possible) I can only see dx accessories on the amazon uk website and not the actual machine. If anyone has used a kindle dx in this way I'd be grateful for your opinion on how easy it is to use and any negatives. I usually download load research papers on to my computer in a word format rather than pdf which I gather you have to use for the kindle dx - what are the pros and cons of this? Also is the memory sufficient for a large number of papers? Thanks!
