Well....I have spent some time(probably too much time) on all three reading apps mentioned. Conclusion> I just purchased MapleRead(love the curl effect
) and Marvin 3 (neat "Reveal" annimation). I think its great that Marvin 3 lets you use their reader for free with that little banner that isn't even annoying. I just couldn't resist paying for their app, and I do really like both Marvin 3 and MapleRead!!
