I have a kindle, iphone 4, and ipad 1. I like reading on all of them, but I mostly read on my phone. This is mainly because I read in bed at night, and having a light on for the kindle would bothers my wife trying to get to sleep. I rarely read with the ipad just because of size and weight. And to a lesser extent the non-retina screen. Some people are really bothered by reading a backlit screen, but it doesn't bother me. I use the black background with white text and turn down the brightness and it works pretty good.
