Hi Ill be getting a rMBP. It will be my first OSX device. I'm a bit of a gamer and I want to play some pc games like fifa 2012... the problem is that the 256 gb ssd im getting may turn out to be a bit to small. So Ill get myself a extrenal hardrive probably this one http://www.macmall.com/p/LaCie-Hard-...42~pdp.giieaba ok lets say I have it, and i get windows 7 on my mac. Is it possible to install games and programs on the external drive at all? two can both of the systems use the external hd to install aps,games... Thanks!
