Yes, Vista 32bit is now ready - and it was not just a few months back.
I have two work computers.
One is a Dell XPS laptop (dual core, 4 GB RAM, 200 GB 7200 rpm drive).
I have two hard drives that I switch back and forth
Drive 1 is XP Pro
Drive 2 is Vista 32 bit Ultimate
The XP drive was my workhorse due to video drive support for my NV 7950. That changed with NV driver updates. Now it is all Vista. So much better at everything. Eye One Display 2 installs (v 3.6.1) and works perfectly in Advanced mode. Vista Ultimate has changed so much visually that it appears to be something other than Windows. Love the useful Gadgets, maybe too much!
Other computer is a Dell QuadCore desktop, same 4 GB RAM, 2 500 GB 7200 drives, NV 8600 GTS. Dell 24 inch (1920 x 1200). Again, a perfect Vista 32biit system. Eye One Display 2 installs (v 3.6.1) and works perfectly in Advanced mode. It may be better on the Dell 24 than XP on the monitor profile. I need more info on the Windows Color System, but the other application color (PowerPoint, Publisher) is so good now (compared to XP), not just Photoshop CS3 or the other Adobe apps. Something is very good here.
Hope this helps - just get the latest drivers. Also give Super-fetch the first 3 minutes after startup. The response after Super-fetch loads is rocket fast. Once again, I didn't expect this much difference. Microsoft may have finally got something almost perfect.
