I'm looking for personal opinions from people that own the devices. I am looking at buying an e-reader, specifically the Kindle. I have the Kindle app on my phone and enjoy it, I'd just like a bigger screen. There's the Nook though, and I hear that some people like it. Do you like it? I've used to Barnes and Nobel app and I didn't like it all that much, but it's been a year or so ago, I'm going to re-download it and try it again.
Other than the stores which I can run trial of on my phone, I'm looking for opinions of the hardware. Specifically the WiFi only Nook (non color) and the WiFi only Kindle. How good are the batteries? How prone are they to crashing? Are the screens going to get ruined easily? How are they with PDF files?
