I installed Vista on my system when it first came out I almost have a stable software configuration on my system. Don't get me wrong, I think Vista is great by many some of my favorite programs wont install or run under it.
The following progarms actually install and run great undre Vista:
DVDFab Platinum (No problems, great as always)
NOD32 Antivirus (the best, and I tried em all)
Roxio CD Creator Suite 9
AOA DVD Ripper (minor GUI problem)
GOM Player (free)
McAfee Site Advisor Plus (really great utility)
Alcohol 52 (trust me, you'll need it under Vista)
All of these a great products and should cover most of what people here do with their systems.
Now if only Outpost Pro or Zone Alarm would release a Vista firewall.
