If you've been patiently awaiting the arrival of Windows 8 tablets while staring at your iPad with evil eyes, listen up. Now you can test apps in, and play with, the Microsoft Metro interface right on your iPad. While that may sound awkwards--dirty, even--it's perfectly easy to do using the Win8 Metro Testbed app from Splashtop. With it, you can swipe to switch between apps, access the Charms menu, and all the other stuff you'll be able to do within the confines of a Windows 8 tablet Metro interface. You can find the app in the iTunes App Store, where it costs $24.99 for a limited time. Afterwards, it'll be bumped up to $49.99, doubling in price. You need a PC running the Windows 8 beta for the app to work. Check out a video demo after the break.
