We've already seen the Android App Player leak out, and now the BlackBerry PlayBook has taken one more (unofficial) step towards being a full-fledged, psuedo-Android tablet. While it's described as a "proof of concept," the video above from CrackBerry forum member Lawguyman shows that the tablet is at least capable of running the Android Market and downloading apps, albeit with a few PlayBook-induced obstacles -- check out the furious swiping around the 1:30 mark. Here's hoping for a slightly more official solution before long.
