Not me, but I have an ipod touch (came with my new macbook pro-- just got it about a month ago) and a blackberry along with my sony reader, and I have all three of those things loaded up with books. About 25 on my touch, well over 300 on my sony, and probably only 10 on my bb. I definitely use all three for reading, depending on my mood and my location, etc. I almost always have all three with me, in any case.
Iʻd like an iphone now, mainly because I could sync it with my touch and mac
