I buy a lot of comics, but I'm not a collector. Those comics go in the trash after I'm done reading them. Digital really wouldn't be that much of a transition for me.
The two holding blocks are: 1) I don't use a tablet reader (currently on a kindle) and 2) I'm still loyal to my small comic shop.
That Marvel deal ($60 bucks for their entire year's worth of comics) would do a lot to bring me into the digital market...if it were DC making the offer. I don't read all that much Marvel these days.
