I planned on getting a copy of Windows 7 for my rMBP. I was actually promised a copy from a friend, but he no longer has any copies. It is so close to the Windows 8 release so I don't know if I should wait or not. I hear bad things about Windows 8. There is certain application I need it for, especially gaming. I've spent so much on this machine, that I wasn't expecting to spend even more. I mostly plan on using Boot Camp but is it recommended to get Parallels as well? Also does the rMBP operate even when the lid is closed in Windows 7/8 like how it does in Mac OSX?
