For months I have been struggling with Vista. I got an AMD 64 bit chip, and dammit, I was going to have a 64 bit system, that still ran the stupid PC games. I finally gave up and went back to XP.
-networking hopeless, even with all the weird 'tweaks'
-no games ran (hardly any)
-kids yelling at me
-no PCI cards work
The final straw was that the graphics driver suddenly went sour, and nothing I could do to reinstall it worked.
