Holy crap at some of the post in here.
You are not going to get a magical overnight change but just like any new platform over time it will grow and eventually you won't need windows anymore if you so desire.
it's like a console gen change .., the ps4 can not play ps3 games but over time all new games will be made for it.
The big difference is unless something bad happens there will always be games on windows as well so that means *gasp!*. You will have More choices.
