Comics by Comixology is the best app I know for reading comics and graphic novels. Downside: Frequent crashes./QUOTE]
Have you tried
Comic Zeal? It has performed flawlessly so far (and I read a fair amount of comics/graphic novels weekly). The biggest downside is that its a paid app ($8), but its worth it (I sideload all my comics, BTW).
