Why Windows?

[BlueRevolution]

Games. That's the only reason for a lot of people.

If you do get a Mac, don't put Windows on it for at least a month. That way, you'll have a chance to find all of the Mac apps to complement your workflow, and when (if) you put Windows on there you won't be constantly booting back and forth because you're still dependant on your Windows apps.

There is always iWork as well, it can read Microsoft formats.

Literally the only reason I use Windows is for Steam, if it wasn't for that, I wouldn't use it.

CrossOver has official Steam support.
