Why use Service Pack 2, or 1? Im still using XP with no service packs (yeah you can enable USB 2.0 without the SP). Service pack 1 made my system take FOREVER to boot, even after running bootvis. And now hearing about all these issues SP2 has, why use it? It adds a better firewall and some security updates, so what? Those security updates can be downloaded individually, so you can pick and choose them if any screw up your system. Although I must say, back when I was a Windows 2000er, those service packs were always nice, 1-4.
