well if u compare hw do yu feel is windows vista then others

when i first installed vista, i felt good but when i used it i felt than winXP is better in usability for so many reasons..so i am gona use winxp for atleast more 1 year install good AV (avast recommended) and a good firewall and dont worry its all secured nothing to worry about.. vista's graphics are good but what about low end systems? if you enjoy trying different operating systems do try Mac OSX for intel processors =)
