Strange.
That's exactly what I said when Vista came out.
The disaster that was Vista 1.0 is one of the main reasons that so far I have only upgraded one computer from 7 to 10.
However, with the first Vista service pack, or actually with the beta of the first service pack, the many problems I had been having with Vista all went away. Microsoft first made a godawful mess, then cleaned up after itself.
After service pack 1 is released, or just before the free upgrade offer expires, I'll install 10 on a bunch of computers.
