the writer stressed another good point that when, XP first came out, it was revaloutionary, but then after a year or so of owning it, you found yourself realizing that any [bleep] with a computer can send a virus to your computer. and then you are faced with the horror of re-installing XP just to have it do the same thing over and over again.
Service pack 2 was a start. but it didn't fix everything. personally, i would like to see some sort of an effort to convince the people that these errors and bugs found in XP can be fixed and won't be an issue in Vista.
