Comic Reader Mobi
Yes! The Comic Reader Mobi app lets you put your own comics (zip, cbr, rar, cvz, pdf support) and read them on the iPad. You can either use the app's built-in FTP server support and FTP over files, or you can use iTunes' new file transfer, which is a lot easier. In either case, once the files are on, you can swipe (or tap) to go between pages, and it'll even auto-detect which orientation to place the image in depending on the image size. This solves the problem of needing to go to landscape view that we complained about in the Marvel app reader. The only downside is that this is $15, but if you get your comics from somewhere other than Marvel's app, then you'll want this. You know what I'm talking about. [iTunes]
Really good comic reader, but pricey.
Apple's free eBook reading experience is polished and mostly as intuitive as you'd think Apple would make it. I didn't find myself missing the Kindle's page turning buttons, given that small swipes worked so well. It's a tactile experience (for a glass screen) that only needs a decent bookmark to finish off the nostalgic paper feel. But the iTunes book store? Somehow Apple has made shopping less fun than reading a book. Full Apple iBooks review here.
