I'm looking to sit in the front of the room and record what is going on the board during a lecture with a clampshell device. Not tripod or camera if possible. 1. What tablet has the best camera in general? And can be paired with a clampshell accessory that gives you at least 0 to 135 degrees (roughly) and is stable? I don't mean a kickstand- I mean a true clampshell.
