I don't mean to paint a doomsday scenario, I know that if google turns evil we'll find a way to break out of it.
It's just that in my opinion MS' lock in set the computer industry back at least 10 years. I think we could have a lot more advanced technology today if we hadn't been locked into an inferior platform for so long (today it's not as inferior, but imo everything pre-win2000 had superior alternatives).
I would hate to suffer another set back by too many people betting on the same horse again.
