I don't understand why fusion is better
I've been a long time user of Parallels, and it's been pretty good. I have had a couple of times when you launch parallels, it switches on the VT extensions, and gives me a kernel panic. It also lacks 64-bit OS support.
However...
Having tried Fusion for about a month, I have become annoyed with it. Performance when running is similar to Parallels, there is no real discernible difference. But when you load a suspended state, Fusion issues a command in windows to reinitialize the VMware tools. This command prompt window stays open for the better part of 4 min, meanwhile the windows system in unusable.
This is repeatable...
Despite this, there is no doubt in my mind that VMware will have the better product as Fusion matures... it is only 1.0...
