Just came across
http://www.seewindowsvista.com/. Looks like MS has put up a collection of videos to show off Vista. It's pretty funny seeing
Tom Skerritt introducing the demos. If you just sit on the home page for a bit and dont click anything he starts nagging you. :)
Most of the demos seem really geared towards business and all are using WPF heavily. The virtual books from the British library look really cool even if it does harken back to the
Saturday Night Live sketch. Go on over and take a sip of the kool-aid.
