Earlier quoted context omitted.
Windows XP even before SP2 was a _delight_ compared to the true train wreck that shipped on consumer PCs before it: Windows "Mistake Edition" Me.
It was also preferred (by most people, at least) to Windows Vista, the product that usually shipped on PCs after it. It was an almost undeniable local maximum in Windows releases from the consumer side, which does make some of the fond memories make sense.
It often feels like the biggest difference between Vista and 7 was actually time. As such, the cheap computers 7 shipped on were much better than the cheap underpowered computers Vista shipped on (despite both OSes likely having similar realistic requirements).
Win7 kinda was the SP2 of Vista more than a major version.
