I am actually impressed so far. We have vista on the laptop, but I hardly ever use that.
My XP installation has been solid, so I never bothered going to Vista. I will go to Windows 7 though. I really like it. Like any new OS, people get frustrated when things are in different places.
I set it up with a dual boot configuration to run alongside my XP. It was the quickest windows install I have ever done. Up and running very quickly.
Early observations/problems.
1. Did not detect/Install my Xfi Extreme Music.
Solution - Download 64 bit Vista drivers from Creative. Run in Vista compatability mode.
2. Did not detect/install the SM Bus on my P5Ke/Wifi AP
Solution - Download chipset drivers from Asus. Again, must be run in compatabilty mode. (Vista)
3. Did not detect/install my Canon N650u scanner.
Solution - Throw it away, as vista drivers were never released
Just a suggestion, but perhaps we could have a list of problems/fixes somewhere. I would imagine some of the issues would be quite common amongst us.
