The switch is painless and transparent to the end user and they can do everything and run any piece of software they did before the switch. Same goes for large scale business roll-outs as well as the home desktop.

So if I make a giant scrotum monster with a phallus beak, and upload it to EA's servers, can I sue them for offering sexually explicit material in an all-ages game?

I'd like to see MS just make software. Strong, reliable OS's and apps' that run well on all PC's and function well with legacy apps. OK, now stop your chortling. Instead, MS focuses on trying to win at everything, and they usually start out WAY behind. The two most glaring examples that come to mind are IE (back when Netscape had already established itself as THE leader) and Zune, when the IPod had already totally OWNED the portable music player market. I'm sure there are others, but that's what comes to mind ATM. I'd like to see MS stop trying to win EVERY race, and just focus on the one's it know's already.
