I ordered a 2010 15" MacBook Pro i5 2.4 with the 320GB hard drive and it should arrive tomorrow. I am upgrading from an old Powerbook G4 so I have never had the option to play with Boot Camp or Parallels, Windows on a Mac is new to me so I'm seeking a little beginners advice. I want to know what size of a partition I should use for Boot Camp with Windows 7 64bit. I was thinking about 40-50 GB but I'm not sure if this is too much or not. I am mostly planning on using it to run games from Steam (what isn't available for Mac) and maybe a few minor programs. I've never played with Windows 7 but I've heard it's pretty good and I'd like to familiarize myself with it a little. Thanks in advance! PS: I searched around on the forums but I couldn't quite find the answer that I was looking for so I apologize if this has been addressed elsewhere and I just didn't see it.
