What ever you do make sure that you have windows... Linux is great, but it cannot cover all your needs.

I was using Linux mint 13 for my main OS for about 2 months, which forced me to learn python and caused me to not play any games ( which wasn't that bad). But in opposite, linux gave me a lot of cool experience with pen-testing tools and other cool stuff.

Right now i am using windows 7 and ubuntu as dual boot.

Also if you are programmer or want to be one, i'd say that windows best feature is .NET framework & Visual Studio.
That's actually why i wanted to switch back to windows.
