I'm changing my system soon and I can tell you that I'm very, very happy that most of my games are on Steam. I remember that manual installation from DVD used to take minutes to hours, and I just don't have the time for this any longer.
Right now, my biggest nightmare are VST plugins. They are in fact the reason why I didn't upgrade my PC from an i7 920 for years. I estimate it will take me at least a week of full spare time use to deinstall them on the old machine and re-install them on the new machine. Steam would make many people a huge favor if they managed to enter the pro audio market, which still comes with their own installers, licensing schemes, DRM, spurious hidden support services, etc. All the bad stuff, exclusively for honest customers.
You need a pretty hefty net connection to download a complete library in a reasonable time. My computer is a little under powered so i look at lighter games, they're all over 6GB, some are 25GB ... there's at least 3 times I've gone to buy a game, following email offers, and thought it was just too large.
I probably need to look into QoS again, but my ISP's router has it locked down.
