spec sheet delicacies that RIM has in store for its PlayBook, but here are a couple more details to complete the picture. The PlayBook will indeed match the iPad in having 16GB, 32GB and 64GB variants available, and will also come equipped with a pretty huge 5,300mAh battery. That'd be a generously proportioned cell for a full-sized laptop, we imagine it'll turn the PlayBook into quite the endurance champ. Beside those tidbits, there's another video appearance by the tablet that we weren't allowed to touch just after the break. You know you wanna see it.
