I have the Kindle 4 (one before the touch screen one) and I have to say it's better than I imagined. I put off getting a Kindle for ages because I wasn't sure on how good the proof-reading was going to be - turns out it can be pretty hit or miss on a few books (very few in fact) but I've never actually experienced any myself it's just what my girlfriend told me. She said there are a few Discworld novels that have a few typos and such but oh well.
So far my Kindle is all I need in terms of features. Looking for book recommendations but not the thread to look for them
The text on that new one looks crisp as a nun's undercrackers
