Well I've read the forums for a few hours now trying to figure this out and searched the internet. For the life of me, I can't seem to get a concrete handle on this so I'll ask it here. If I have a new I-5 13" MBP with 8GB RAM, using Windows 7 with Fusion or Pararells, will it slow the computer down and will the computer run hot? Also, even if Windows 7 is running with Fusion or Parallels, the gestures and being able to darken the screen (using F1) like in Mac OSX would be the same as Mac OSX since one is actually running Mac not Windows. Is that true? I had a 15" MBP about 3 years ago with Windows XP and Bootcamp. Ran fast for sure but very very hot. I would like to virtualized this time. Thank you.
