Hi all, I am new to Mac, and hence this question. I am on a learning curve trying to grasp all that the mac os offers. I just brought by first rMBP and i would also like to install windows 7 on this. I realize there are several options to do this, BootCamp, Parallels etc.. probably also on the boot? Anyhow, whats the best option to do this.. with least amount of CPU and memory consumption? or will i have to sacrifice on one while i run both mac and windows together? PS. at the apple showroom, i was able to use three fingers to swipe right to windows desktop.. what was that? so, whats ur most sought out method?
