That Marvel deal ($60 bucks for their entire year's worth of comics) would do a lot to bring me into the digital market.
Only 60$? Is that for current issues or for their back catalogue? If it is for current issues then it's a pretty sweet deal and cheap to boot.
With the proliferation of tablets i can see this being a real alternative and back in the day when i still read comics regularly i'd have easily broken this 60$ barrier in 2-3 months, depending on what's going on maybe even in a single month (at 3-4$ an issue not that hard to do).
