To be completely honest, once you start using the Mac OS, you really wont want to worry about installing Windows. Nor will you have any desire to. At least that is what I experienced.
Once I made the switch last month. Our old Gateway laptop is just sitting gathering dust. You have to understand though... I can do everything I need (programming, graphic design, word processing etc..) all on the Mac just like the PC. If I was still into Computer Gaming, I would be a bit hosed
