As I expected, there's lots of really good feedback :-)
I should have clarified that I have lots and lots of tablets and phones and all those sorts of devices, but I've never had an e-reader and I'm curious enough to at least want to try one (mostly for battery life, eye strain, and general impressions). Ideally I could just buy one and it would be great, rather than having to try a bunch of them before finding one I like :-)
