Sales and games I can get no where else are the only reason I use Steam. Normal prices are too expensive, and I would never pay more than $10 for just a subscription to a game. It's crappy DRM that doesn't work well half the time, especially in offline mode. It's only 'good' feature is it's social integration, but I play single player games and don't really use it. So it's pretty much at the bottom of my digital distributors I use anyways: GOG, Gamersgate, Dotemu, direct purchase from indie developers, or just buy retail, then Steam.
