RIM and AT&T have scheduled an event for next Tuesday and the world is expecting the launch of OS 6, and the Slider. If you can't wait until Tuesday you can grab some OS 6 goodness from this video review of the BlackBerry 9780. Driphter has put together a nice five minute review of the 9780 showing off the WebKit browser and app switcher among other things.
The reviewer notes that the software they are using is pre-release so there are sure to be some tweaks to the final OS 6 version. This looks slick.
