I sort of see digital comics in their current form as renting indefinitely, not purchasing outright. But when I think about it, there are an awful lot of comics that I read once and then toss in a box never to be seen again. Under those circumstances, the risk of losing those digital comics to a combination of DRM and company whim and/or business failure doesn’t make much difference.
Sure, there’s no resale value when I’m done with those comics. But let’s face it: there’s very little resale value on most of the physical comics I’ve bought and read once.
I still buy most of my comics on paper, but there are a few series I’ve tried out digitally, and so far aside from the fact that ComiXology could really benefit from a usability expert overhauling their UI, it’s mostly worked out so far.
