The only concern I have with Steam is I played MW3 on it, and the constant having-to-be-online and logged-in with them was a bit of a pain. That's not even taking into account if their servers are ever hacked, which is a bit too often for my liking. Something not great about buying a product and getting it home, but before you can use it you have to go online, register an account and stay online all the time. Broadband hiccups and you're kicked out and have to start all over. Don't know about anyone else, but I steer clear of anything involved with Steam now.
