The so-called SideShow technology found in most versions of Windows Vista is one of the few real and visible improvements in the new OS.
Cutting a long story short, SideShow is a protocol that allows PC data to be pushed to small SideShow devices, where it can then be displayed even when the host is powered off(due to caching).
Drivers that allow Windows Mobile devices to function as SideShow terminals aren’t new - but Microsoft now released a developer preview of an official driver that transforms Bluetooth-capable WM5/WM6 devices into SideShow stations.
As of now, the program still is in early beta - daredevils with Vista(/me is excluded) can give it a pop at the link below:
