Yes finally, and I'll be 100% agree with The Unwired there. Microsoft's Windows Mobile Developer team finally made the Vista's SlideShow available for Windows Mobile devices, although it's still in early release or known as beta version.
The official name is Microsoft's Windows SideShow for Windows Mobile Developer Preview v0.01, is an application for Windows Mobile 5 and Windows Mobile 6 Pocket PCs and Smartphones that allows you to use your Windows Mobile device as a Bluetooth SideShow-compatible device. This enables you to use your phone as an extra window into your PC. You can both access your computer's information from your Pocket PC or Smartphone, and control the computer through a gadget interface.
