There has only been one reliable release from Microsoft since 2000.
Seriously - if you pretend that everything between Windows 2000 and Windows 7 never happened, then Microsoft actually look like a badass company with solid products.
What the hell does this crap mean? XP (SP2+) had better security (and compatibility) than Windows 2000, and Windows Vista's security was light-years ahead of 2000 or XP.
