Just upgraded VMware Workstation on my Vista Machine and the Unity feature is great. I also have upgraded Fusion which also includes the Unity feature and greatly improves Fusion on the Mac. Most of my testing has been with Fusion and it’s just a fabulous experience on the Mac. I feel that VMware has made some exceptional upgrades to Fusion which now out performs Parallels. It is great to see VMware putting this kind of work into their Fusion product. I will soon post my overall experience with VMware Fusion.
