ok, time to dig this thread up again.
MS have now released a Vista Upgrade advisor. You can
download it and it will test your system to see if you are able to run Vista. It's still beta btw.
By the sounds of things all the hype about needing a brand new ultra spec machine is bollox. My laptop (9 months old, good spec HP Compaq) passed with flying colours, and is fine for the Aero UI with it's onboard graphics chip.
Currently downloading the just release Beta 2, and will have it running in a virtual machine tomorrow
