I've tried Stanza but don't like the user interface. I much prefer Wattpad.
The things I like about using iPhone as the reader rather than buying something like Kindle is that there is NO WAY I would want to carry an additional device, especially when it is so big with me. A specialised device, no matter how good, will not be the best solution if it does not get carried around and used. Just like my cameras, which is almost never used now. I just about take all my pictures with iPhone these days. Same for my expensive video cameras (yes, more than one), they don't get used anymore. For the same reason, I would not go out to buy a dedicated TomTom GPS device, I guess.
