OK, some people like Vista and some don't. I don't see any need for Vista as long as XP fulfills my needs. The new Vista user interface looks cool, but it also costs a lot of performance. The lack of Open GL support is annoying and leads to a lot of troubles on some PC configurations with Poser7 and other application that use Open GL. Nvidia seems to have implemented Open GL in their graphic card drivers to compensate that.

If you have installed Vista on your PC and it works you're lucky. A lot of people have problems with Vista for various reasons. Often due to a hardware configuration that is only partially useful with Vista or instable drivers.

I installed XP64 Pro on my new PC and I'm very happy with it. I didn't find arguments for myself to upgrade to Vista. People who prefer Vista over XP may do this because of the better user interface. I didn't see other improvments yet, except higher memory and CPU consumption and lack of drivers. Microsoft has still a lot to do to make Vista really superior to XP. On the other hand, Microsoft needed SR2 to make XP superior to Win2k.

So let's wait one or two years...
