OK, I see what you're saying. That there's really little reason for the operating system on a home computer to look and work exactly like the one at work.
I agree. I think as computer users, we're mature enough not to need this level of familiarity. This is one reason that at some point down the road, I hope to be able to use both Windows for my digital audio workstation in my home studio, and some form of "SteamOS" for playing games. Of course, with companies like EA/Origin and Ubisoft using their own game store platforms, I don't see all PC games being compatible with a SteamOS for some time to come.
