Hi,
The last laptop that I have bought one year ago had Vista. I have spent a few days to look at the changes, and since it seemed to be not very reactive, to make the fans run a lot, I have just installed a second boot with XP : the computer has been faster and cooler with XP, so I boot one time a month in Vista, do some things during 10 minutes, and reboot into XP.
It is not bad, but for me, a good customized XP is far better, nicer and simpler.
It is like when OS X has replaced OS 9 (no, it was a lot worst !) : a lot of people (all people that do music that I know, including me) had continued to use OS 9 during a few years until it has been mature (10.3 for me).
The good thing with a double boot is that you are not forced to make a choice, it is safe. You will see by yourself after some time.
