When the BlackBerry PlayBook is released, you will only be able to download apps through App World. Eventually, you will be able to download apps through other outlets. App World on the BlackBerry PlayBook hasn’t been shown running at the BlackBerry booth in CES 2011. However, the image above in a presentation slide shows a new, very clean UI for the PlayBook’s version of App World. We think this version of App World looks beautiful. What do you think?
