I'm thinking of buying an iPhone for my mother as a 60th birthday present and I wanted to get some ebooks setup for her to read and a decent reader. There seems to be several to choose from but i want to get her the easiest one to use as although she's surprisingly good with that kind of stuff from years working on a computer as a receptionist, she still has limitations and it means less phone calls to me for help if the app is user-friendly and easy to navigate.

Somebody has mentioned Nook to me as an alternative to Apple's own iBooks app, as well as Kindle and Googles. I'm not a reader so have no experience of any of them. I've heard several people swear by the Kindle app so is that the best of the bunch would you say?

Thanks,
Manny
