I've used Comixology and Marvel Unlimited before. Marvel Unlimited is a travesty on Android tablets, which is really unfortunate, because a subscription service like that is probably the only way I will consistently read comics.<p>Comixology's app is certainly better, but it's tough to shell out the money for something I could be done reading 5-10 minutes later. It'd be nice if they could get together a subscription service like Netflix, but for the smaller publishing houses like Image, since DC and Marvel will obviously go their own way.
