I did that because as an I.T. professional I felt I should be familiar with Vista. Now I am sorry. I should have put Vista on an old machine instead and bought Acer with Linux instead of Toshiba with Vista because the *#!#&&$# manufacturer of its wireless adapter and other peripheral suppliers have not developed drivers other than for Vista.
So now I use the notebook primarily as a remote client to my desktop or work in virtual XP machines.
That’s my understanding of the general hardware situation wrt drivers, so I’m waiting a while even though I could use a new laptop to replace one that was old, partly broken and had to be returned to the owner. Used laptops seem to be overpriced compared to new ones. Dell has a Linux offering but it is a little early yet to try that.
