I wanted to get back into reading and I have absolutely no freakin' clue about these readers. So my choices are obviously, the Kindle, the Sony Reader, and the Barnes and Nobles one. I don't know much about them, but upon glancing at the sites for each, I noticed the Sony one plays MP3s, but I feel like the Amazon one would have access to more content (but that's without anything to back that). Truth be told, they both are up to date on Drizzt books, which is all I care about. But the kindle has a compatible app on my iPhone, which I won't use much, but it might be good for continuing a book while I'm on the toilet. The Barnes and Nobles is probably my last choice. Anyone use these on a regular basis?
