Anything using Steam as DRM is worth around 10 euros at most, anything using almost any other form of DRM is worth around 5 euros at most. Typically the sums are about half the maximum, meaning Steam is around 5 euros at most, and others are around 2.50 euros at most. So far I haven't bought a single game that uses any other DRM besides Steam but I'm still waiting for some games' prices to come down (Far Cry 3, I'm looking at you). I would've bought quite a few games more if it weren't for DRM but alas, DRM reduces the value tremendously for me. It's almost impossible to completely avoid DRM these days but patience helps a lot.
As for consoles, I've bought some digital games on PS3 too. Not many, mind you, but in some rare occassions where it was cheap enough. I prefer physical on consoles, though, because there's pretty much nothing I can do if the download service goes down any time in the future. On PC I at least have (questionable) options to help me if need be.
To sum it up, I strongly prefer physical even with all its downsides and I'm very strongly opposed to all DRM (because it simply doesn't work), but I can buy games with DRM. DRM just reduces value tremendously and I wait a lot longer before buying. In my opinion, GOG.com is quite possibly the only download service worth using without a question, and that's counting ALL kinds of download services (that I know of). That's including games, music, movies, etc. I'd love to buy music digitally but I'm not happy with watermarking and I don't know of any watermark-free music download services that would have the artists I like in their selection.
Also, the poll is too black and white unless that was intentional.
