Me and my PC-Loving friend are having a heated debate about what OS is better and pretty much are Macs or PCs better. I didn't think I would have much trouble finding people who love Macs here so if you want to help destroy a PC-loving persons debate, please, tell me some of the cool things Macs can do. Such as key combos and what not. Things like ctrl+optn+cmd+8 makes the screen negative. Any cool MacBook key combos or anything cool about Macs are welcome. Thanks
