Steam is, essentially, a nanny. It needs to be turned on if you want to play games, it sorts them into its own directories, and it automatically updates them. Some consider this convenient and easy, others find the lack of control the user has to be awful. That is a matter of opinion.
On the upside, a game purchased with Steam requires no physical disk or other form of DRM. On the downside, there's other games that do just fine without any form of DRM and which also don't require Steam. (See Sins of a Solar Empire) Not having a physical disk is also a downside, as if you lose your Steam account (accidentally or by being banned) or if Steam's servers kick the bucket in the future, then you don't have the games anymore. The DRM issue is also mitigated in that you can remove it through various methods on certain games you also own the physical disk to.
Steam also has achievements, which some people like, and "social" features such as being able to chat with others across different games.
Personal opinion: Steam reduces user control, and it's requirement to be turned on is something I can't live with. In addition, I prefer having physical disks. Achievements are fun, but they can be handled within the game itself just as well (e.g. Dragon Age: Origins). I don't want to chat with others when I'm playing video games, especially because it would break any immersion. I can update and install my own games just fine.
There's Steam-like services which are less invasive, such as Impulse. Same deal, with allowing you to buy games online and download them, but they don't have to be turned on to play and you remain in control.
