i've voted "avarage", why? sp2 includes a lot of new technologies to enhance XP inet experience but... i hate that tcpip.sys file that prevents me to open many connections: this is the way m$ wants to prevent vulnerabilities? minimizing/slowing connections? the enhanced firewall it's a very good idea but... i hate that security center. the common user don't need it if he's not connected to the inet and also it's annoying that tray icon, if it's not enough, it saves a lot of vital information about your vulnerabilities like the AV installed in the registry. now it isn't exploited by any1 but "a malicious user blah blah" perhaps some day... the worst thing, what about the apps list that sp2 hangs/blocks/don't work/need to reinstall and so on...? and finally my best pro: it includes all the WU patches released to date.
