See, this is the problem I've had not just with the digitization of comics but with video games and films as well. I wouldn't be adverse to paying for downloads of either, but the pricing is usually, at best, standard retail, so it seems stupid to buy a digital copy of something I can get cheaper on sale at a real store and have a hard copy.
Comics are a little different, in that they're more disposable than DVD's. They're fragile and stuffed with ugly ads and unwieldy to organize.
Still, I do the exact same thing you do (but with paperback trades more than hardcovers) and I'll likely continue to do that until digital pricing drops to something reasonable. I think DC has the potential to open up to a wider market than the current insular fanboys, but they're going to have to adhere to some reasonable pricing first. This stunt would be the perfect opportunity to set a lower price threshold. I guess we'll see what they do.
