I specifically like this quote coming from Intel:
Yeah, right. I'll believe it when I see it. I think that this virtual machine stuff will be extremely dependent on hardware resources so I doubt that you can have many high-performance VT's going at one time.Think of users running a Windows-based media server, one on VT-hosted virtual machine, while playing a 3D game in a second Windows instance on a second virtual machine, Frank Spindler, Intel's industrial technology programs director, said yesterday. That way if the game hangs, you don't lose the server functionality.
Second issue is what will Microsoft think? Will they legally allow users to install a second instance of XP on their machine without paying? Of course most people don't care but MS is cracking down on illegal use of Windows and I can only assume that they will increase that activity in the future.
The good thing about this is of course that people can mess around with Linux without going dual boot or second computer. That way they can have best of both worlds - and Linux will get a larger coverage on the desktop.
