Ok, so I was planning on getting Windows on my Mac ever since I was planning on buying a Mac. However, I keep reading that you need a Disc drive to install Windows. Can you install it digitally or do you have to buy a disc? Also which version of Windows should I get if I plan to mostly just play games on it with the occasional need it for a program? And is it actually really hard to get Windows on a Mac? I keep reading that mouse, keyboard, and sound usually don't work. That people just give up on downloading Windows. Finally for BootCamp I have to download the latest one right? I'm buying the most recent 15" Macbook Pro Retina.
