I'm trying a month of Marvel Unlimited at the moment, and it's a really nice service in theory. The downside is that I'm limited to reading stuff in my browser. I don't have a tablet to try out the app, but it has a smart view feature that is supposed to just pull up each panel to be able to read it easier... and it works okay sometimes. Other times, it'll cut out half of the text from a panel or things like that. Also, comics on the website can be organized out of order. Such a pain.

On the other hand, I get the chance to catch up on Runaways since I've only read the first volume. Fun stuff.
