Sorry to say that Vista is NOT ready for primetime if you have many network devices and are a PC gamer. When I began using Vista Ultimate for real (after playing with betas), my external drives were not recognized, leaving me without a backup solution. Games produced prior to 2003 would not run. Upgraded graphics card to the latest and greatest and decided that Vista should be reserved for "Vista Only" games (to come). Had to buy a full retail version of XP Pro since Vista won't dual boot with an OEM version of XP. Now have best of two worlds, tweaking both OS's to suit my preferences. Caution: There is a specific sequence of steps when creating a dual boot with Vista. So I am very patient, no complaints, since I have my cake and I can eat it too...LOL
