Steam with the window being open, 100MB of RAM, with it minimized to tray, 20MB. Chrome is using well over 500MB with 4 tabs and some plugins. This is not an issue unless your PC is ten years old. For the rest you can set yourself offline (though why have friends if you don't use it?), stop it from booting with your system, remove the news on start-up and make it go to your library right away. You can also disable automatic game updates if you want to play a specific version of your game (and yes, official patchers work just fine on Steam games and finds the path automatically near always).
Now yeah, Steam is DRM but I love it to death. I don't even want to buy games anymore that I cannot add to my Steam library and non-Steam games I start-up from there too (even Origin/Uplay games I own outside of Steam). I have games on GOG, GamersGate, GreenManGaming though I find it a pain to manually download these games (don't get me started on GMG's capsule client) and then to make sure they are patched to the latest version. The main benefit is that Steam keeps everything centralized and is generally reliable, or at least a lot more than Origin and Uplay. If talking about physical games, I don't even have room to store my ~350 of them and I'll be damned to go through the trouble of finding the one I want, installing it over DVD, manually finding the latest patch, download and install it and then keeping the DVD in the tray each time I want to replay a game.
If Steam breaks, I got 300 games installed I can play in offline mode. If the Steam service ever stops entirely, don't even try to tell me there won't be a another (less than legitimate) version that'll launch your installed games within the hour. Though I don't see how this is really an argument, the same goes if GOG or whatever goes offline and you don't happen to have a back-up of the installer. The main thing is that I don't have to worry about more draconian DRM like AC2's always online nonsense. Though it remains ridiculous that Steam games may still require other DRM like Uplay (Far Cry 3, Driver:SF, Anno 2070) or god forbid, GFWL (Dark Souls, Lost Planet 2, Resident Evil games).
All that said, sales aren't really an argument for Steam as these occur everywhere. Prices are usually on the high-end outside of sales too, but from what I understand that's mainly the publishers' doing, deciding for how much its games should be sold. The primary issue with Steam is the same one most digital distributors have, the inability to re-sell games as used. The other glaring issue is the (from what I heard, I've never needed it) Steam support center for being generally slow and unhelpful.
Bottom line, it's not perfect but it's a whole lot better than the alternatives: fragmented library, time spent installing and maintaining said library and horribly intrusive DRM that actually makes you jump through hoops like: please make an account/login and register your CD key for each different publisher. Also note the 3 machine activation limit and if possible, please be online all the time; 1 dropped packet and you get to restart your game. Oops, server is down! Guess you can't play at all! Even though you have everything installed and registered...
