Yeah I've got a friend who is a SteamHead, for him this is really convenient. I don't really care for that. And there is actually an alternative to running a client: *Last year I got it of GamersGate - no client *This year - http://uk.gamesplanet.com/buy-download- ... 92-34.html
Saves me from waiting an extra week and shelling out an extra 20$ for the retail version (It costs 45$ - 60$ here...)
