Case in point: Back in 2007, I looked at Windows Vista Home Basic and determined that it could run well on an older machine with limited resources, including 512MB of RAM. I never tried it with Vista Ultimate, nor would I have bothered. And since I don't have that 2002-vintage test machine set up, I haven't repeated those tests with Windows 7."
