It's a tiny bit slower on my PC. Kind of the nature of things......DOS would probably scream on this computer....even Windows 3.1 would be instantly fast compared to WinXP. Of course, who wants to use that.
Someone had a video of SolidWorks 95 installing. It took just seconds to install. Fast for sure but you'd lose quite a bit of functionality.
Even after using 2008 just on and off for the last few months, its beginning to be painful to use 2007. The pop up menu is just too quick and find myself greatly missing it when doing "real" work in 2007.
