I've got a list of games to play that I just can't seem to find time for but once I get through that list I will buy all new games through Steam. Great specials, achievements, having a game list that's ready to install and play any time I want to, forums with answers whenever I need them, no need for discs that take up space, a huge collection of both old and indie games that are sometimes tough to get hold of.

Awesome really.
