Vista is a horror. I bought a new laptPC in early March. The computer crashed on the first day of use. It has crashed repeatedly ever since. All sorts of screwy things keep happening. It is a complete and utter disaster.
Bought mine about 5 months ago and have had one crash. Considering all the strange software I run and a lot of old versions I’ve installed from my win98 days that I still use, I’m happy with that.
BTW, one of the first things I did was rip out Norton - I suspect it puts a lot of hooks in where Vista dosen’t like them and fights for control.
