XP Mode in Windows 7

Microsoft finally announced the XP Mode optional feature for Windows 7: http://windowsteamblog.com/blogs/business/archive/2009/04/24/coming-soon-windows-xp-mode-and-windows-virtual-pc.aspx. By adding an XP virtual machine to your Windows 7 installation, you have the perfect fallback position for applications that won't run under Windows 7. Just install an application in the XP virtual machine and publish it to your Windows 7 All Programs menu. When the published application runs, it will appear to be running from Windows 7, but it will really be running from the XP virtual machine. You don't provide XP media or a license. This is a free addition to WIndows 7.

Sounds great!  Have you played with it much?  How big is the perf hit?

Performance hit, compared to running XP in the first place?  Which is slower, an African tortoise or a Galapagos tortoise?  :-)

Wow - now that's a great feature.  I hope Microsoft keep it in for RTM.

I haven't noticed a performance hit, but I have really good hardware. On a 3.0 GHz quad core system with 8 GB of ram and multiple drives, performance is excellent. But on machines like that, performance of just about everything is excellent. This level of machine is fairly common for people who build their own machines.
