OEMs also shipped Vista on laptops with as little as 256MB of RAM, where the silly thing was immediately deep into swap space (on a slow 4200 or 5400 rpm 2.5" spinning hard drive) immediately after booting. It was the most excruciating experience.
And on the other hand 4GB or more of ram would require Vista 64bit, which today remains the most crash-prone and unstable leaky bucket of an operating system I’ve ever been subjected to, at least in the first year of release.
