Personally, I liked the old versions of Windows better as well ... Windows XP, 2000, NT 4, 98 and 95 were pretty user friendly. Vista appears slow and convoluted to me, and I find Windows 7 confusing (but other people do seem to like that one). MacOS X is also pretty user friendly. Many modern Linux distros are pretty user-friendly as well, like Ubuntu, Fedora, Debian and OpenSUSE. Solaris and OpenSolaris is user-friendly too. FreeBSD and OpenBSD too (once installed and configured properly). MorphOS and AmigaOS 4 are user-friendly. Haiku (when it's finished) will be user-friendly too.
Nowadays, there's only few OSes that aren't user-friendly, IMO.
