I've recently purchased a PRS-505 (which I really enjoy using), but I'd like to also try the ebook experience on a PDA. This is no reflection on the 505 or eink devices generally, but is bourne out of curiosity about how the experience would differ - a comparison would also be useful for a study that I am undertaking in work wrt ebooks too.
I'm hoping to pick something up on Ebay for £50-£75 and have narrowed the choice down to:
Sony Clie TH55
Sony Clie NX70
Does anyone have any experience of using any of these specifically for ebook reading and do you have any comments that could sway me in one direction or another, or indeed, are there any other PDAs that I should add to this list?
