In March I purchased a Gateway with Vista from that nice BF.net fella, Jason21nl. As nearly all of the units that they (Best Buy) sold at the time already (only) had Vista, it was hard to heed his warnings about Vista, so I bought the system and hoped for the best. Yikes. The biggest problem, and it's a biggy, was the graphics card. In my case, it is an nVidia, and it simply just wasn't compatible with Vista, plain and simple. This despite the label on the box saying it was. It took months and months before they released a driver that was/is stable enough, and it's barely that. Depending on usage, I would get blue screens of death, lock/hang ups, freezes, etc. on average of about 5-10 times a day. Just ridiculous. Pretty sad that I had just bought this good but not uber rig and I spent nearly all my time at the nVidia forums looking for answers. It's finally pretty stable now (knock on wood), but it was shear madness for 4 months or so. There's still quite a few apps and hardware that aren't completely compatible with Vista, and the real kicker is they may say they are. Lots of lists out there to check, but I can tell you already that some don't work, despite what the box says. I like Vista, it's might pretty, has some real nice features, but to be honest, if I had known then what I know now, I would've gone with XP and waited a year or so till they fix all the bugs. It's just the nature of the beast with new OS's. At any rate, if you decide to go with Vista, post it here and I'll list all the sites I have bookmarked to fix known probs with Vista...little tips and tricks.
