I just found the reason why I’m going to slap down almost $200 bucks for VMWare Workstation over Virtual PC: Unity.  I am using a coworkers VM to help on a project he’s been working on, but he uses VMWare and I use Virtual PC.  Instead of buy a license I’m using VMWare Player.  Well I found option under VMWare called Unity so of course I clicked it.   Well it’s possibly the coolest thing I’ve seen ever. 

Here is my desktop with VMWare running as normal:

and here it is with Unity:

All of the windows/applications that were active inside the VM are now native windows in my host.  Also, when you go down to the start button, a second Start Button with the name of the VM becomes visible that allows you to start other apps in this same mode.  I don’t care what you say, that’s just awesome.
