Actually if you revert back to an older OS, the PlayBook is much quicker.... but probably less secure. Would be nice if we could at least customize the OS at little.
Mine was mainly being used by my grandkids for a few games and movie. Now even they don't touch it very often as they both have iPads and the games a much more refined and entertaining. And even at 4 years old, they know what Netflix.... The PlayBook gets dusted off now just when we are going on a long trip and they don't have internet.
