Splashtop’s Win8 Testbed is “the only app that allows you to experience the Windows 8 Metro UI on an iPad." It works by downloading the Win8 Metro Testbed app to your iPad, downloading and installing the Splashtop Streamer app to your Windows 8 PC, and connecting the two over the network with a security key.
The software costs $49.99, but for a limited time, Splashtop’s Win8 Metro Testbed is available in the iTunes App Store for just $24.99. Check out the promotional video below to see it in action.
