Just picked one up for my girlfriend as a sort of anniversary present. She was quite surprised. So far she's been loving the thing. She likes the e-ink display and has already been putting it through the paces. I think they're pretty cute and might even try to borrow it from her sometimes to actually read a regular book (maybe). She's very excited to bring it on her trip with her later this year and it's been very easy for her to figure everything out.
So far it gets a big thumbs up recommendation from me. I'm going to try and purchase a book online and sideload it to see how it handles other peoples' purchases but it says it just checks the CC # and it should work, which would be nice since for the most part she'll be the one buying most of the books and the ones I buy which probably be better viewed on my iPad or whatever tablet I get next.
