I tried it, for a few hours. I expect it will work well enough if you have recently made hardware, and the graphics are pretty enough, but in my case I use an Athlon 3 gig chip on a Gigabyte MoBo, which requires that drivers from a supplied Nvidia nforce 3 CD (containing a variety of operation drivers) be installed after the OS installation.
Windows 7 won't allow the CD to run, closing it as soon as it opens. Also, for a reason I never discovered, W7 would not allow a connection to my LAN and internet, and without the network I'm stymied. XP has no such problems, so I guess it means that MS has continued with the lack of support for some older equipment in W7, just as they did with Vista.
