Since getting my PlayBook a couple days ago I’ve noticed the App World catalog growing quite a bit. Today RIM added a new category to the PlayBook’s App World called Test Center. This category is where we hope to find some of the beta apps like Facebook for PlayBook, Twitter for PlayBook, and maybe even BBM Video (fingers crossed). Officially we haven’t heard whats going to land in the test center, but it doesn’t hurt to guess. Currently you will find an app called PerformanceTester which allows you to test your PlayBook’s graphics performance. So keep an eye out for more apps hitting there soon.
