Welcome to the world of Vista. I bought a new computer some months ago and it came with Vista. I've had a number of problems but Microsoft keeps doing updates which seem to resolve many of the problems.
I had to buy the Vista version of several products and a couple of things won't work on Vista. For example, I have an HP scanner and when I went to the HP site to get the Vista driver there was a note saying that they're not going to provide a driver for it. So I had to buy a new scanner.
My opinion - it's still a work in progress, but generally a good operating system.
And even though my new computer is a dual processor, with much faster clock rate, the performance is not that much better. I don't know whether Vista uses more system resources or whether the disk access, and Internet access, is really the limiting factor. We really need to break the disk access bottleneck, either with multiple drives (like RAID) for a wider access, or solid state disks.
But I'll probably stay on this one for many years, like I did with my old computer.
Go into the world and do well. But more importantly, go into the world and do good.
