I was on a white Macbook early last year, using VMware with 3gigs of ram. I recall one of the minor annoyances was the Macbook fans that would fire up quite a lot when I was running VMWare. For a short stint I went back to PC but now I'm back. I invested in a Macbook Pro (base model w/2gigs of ram). I have been running VMWare all day long and I haven't heard any fans -- awesome! Is this due to the hardware or software? I have a 4gig kit on the way; I didn't think VMWare was going to run so smoothly with 2.
