In this video Ady Degany gives a brief demo of image management with Wanova Mirage. Watch the main video we recorded this day here.
The environment in this demo has two different model laptops, both with the same base OS image, but with different application and driver layers. A profile for the driver layer can be built up from the driver library.
Mirage also supports access to your files from mobile devices, and they're working with developer previews of Windows 8 so they can support it when it's released.
