I'm planning to try running Vista on a 5720. I plan to ghost my boot drive first in case I don't want to keep it and I can go back to my current XP Pro setup quickly if needed.

I am wondering what success people have had with this. It seems to me that while there are no drivers listed for the 5720 it shares mostly the same components as many of the newer models like the 5760 and the Vista drivers for those models would be fine. I did something similar to get Vista running on my desktop ULI based system by installing drivers intended for a similar system with the same components.
