Steam is a pain in the b... *cough*. Take Half Life 2 for instance. I bought it on a retail DVD, installed it and thought that's it. How wrong I was! The complete game was downloaded again (several GBs) so I could start playing a few days later ... Updates are well and good, but if I buy a game on DVD I want an instant play after installing and let me choose if I want to update or not. This bothers me about Steam. Anyway, I think it's good that it is now available on Linux.
