iBooks may be a "nice" reader, but it's also lame, inflexible, and arrogant in enforcing its own layout choices on all readers.
I find it unusable for reading books.
iBooks reminds me of Internet Explorer a lot. I believe most iBooks users are only iBooks users because they don't know any better, and because, much like Internet Explorer on Windows machines, iBooks essentially comes preloaded on iOS devices.
