Hey I have a few questions and I just grabbed a 13in 2.4 alu (Yep Im a new switcher) First off, just wow on the Mac I love it to death coming from a PC, Its great to have something that doesnt feel like a plastic toy in my hands! So my goal is to Boot Camp Windows 7 + Mac OS X, I have yet to upgrade the RAM on my unit so its still at 2GB (waiting for my work to start carrying it) and Im also using Fusion 2.01. Now the Question x32 or x64? Which would run smoother under a Virtual Machine from within Mac. I know in Boot Camp 64 would be the obvious choice especially when I upgrade to 4GB but will Fusion pose more strain to the system emulating 64 or would it be no difference towards 32?
