This is the whole reason I want to get in iPad. I want to dig through the entire Marvel catalog while sitting on my couch. They sell an annual subscription to all their content, for like $60 or so.
In just a few days I'm going to drop my ipad and pickup an ExoPC (http://goo.gl/oUqfy). For Windows 7 goodness (work requirements) I can deal with the drawbacks (view angle, battery life). Hell, with this thing I can rock my beloved VLC Player!
