> Windows XP got it right.

I'd say Windows 95 in this context. XP was the first stable version of Windows (yes, the first one deserved to be called Windows 1.0), but the Start menu was working well in Windows 95/98/ME, too.

I'd say the label of stable goes to Win2k. XP was in many ways Win2k with new theme and a more aggressive license verification scheme.

XP would also boot / run quickly compared to NT. It was more desktop focused instead of desktop as an afterthought.
