What do you get when you cross a struggling vendor’s debut tablet with a mobile operating system that has spent the past 18 months running into the brick wall that is Google’s Android operating system and Apple’s iOS? One Dutch developer seemingly needed to find out, so he ported Microsoft’s perpetually-emerging Windows Phone OS onto RIM’s BlackBerry PlayBook. The result is a somewhat responsive slate that gives us a look at what will never be; Microsoft is on record in stating that it has no interest in bringing Windows Phone — emphasis on “Phone” — to tablets. Of course, with the software giant’s next-generation Windows 8 platform on the horizon there is no reason to put Windows Phone on a tablet. But for those curious to know what a Windows Phone tablet might look like, a video of the developer’s PlayBook running Microsoft’s mobile OS follows below. “Gamer109X,” the developer behind this curious chimera, said he plans to release a Windows Phone build for the PlayBook to the public in the coming months.
