This has gotta be uncomfortable for the iPad. Now, Windows 8 tablet developers -- or anyone, for that matter -- can test their apps and play with the Microsoft's Metro interface from within the confines of Apple's ubiquitous tablet. The functionality is made possible by Splashtop, which is known for its remote desktop apps that are currently available for Android and iOS. It seems that a good amount of effort went into this application, known as the Win8 Metro Testbed, which offers the same swipe capabilities that will be available on a native system. This includes the ability to swipe from the left to switch apps, swipe from the right to reveal the Charms menu, and pull down from the top to close an application. Splashtop's Win8 Metro Testbed is currently available for a promotional $24.99 in the iTunes App Store, whereafter it will sell for $49.99. You'll find the full PR and a quick video tour of the app's functionality after the break.
