1) Its usually cheaper, and when its not, its surrounded by excellent deals
2) Supports an excellent service that, when supported, turns around and does great things for games at large. The more people buy their Call of Duties and Bioshocks from Steam, the more Steam can turn around and sell clever, scrappy little indie games that deserve a chance. In addition to being cost effective business-wise, they are an investment for the medium as a whole.
3) Valve does a good job, and by supporting people who do a good job, they can do a good job on a larger scale.
4) Convenience. It is very nice to consolidate on one platform. I have non-intrusive social features that are helpful for even my anti-social self, I get all games updated immediately and automatically, I never lose a game, I only need to log on to 1 service, I never lose a login to access a game I bought somewhere else, and basically everything I need related to gaming is in 1 window
5) As much as people will rant that Steam is DRM, Steam is the absolute minimum that you can reasonably expect a publisher to use to discourage piracy. To discourage piracy, something like DRM DOES help. It's just that there is no difference between a 1 time registering to your account and draconian, limited install, always online BS. You just need to make it so the average consumer will have to go to some dubious website to pirate a game, and that is all the dis-incentive you can expect. Steam is at the perfect level of enforcement
