If anyone could answer these I'd be grateful. Are there more than one model of Headplay? I'll be using them with my P3P. The way I understand it, not all items that appear on the tablet are displayed on the Headplay. No histogram, right? What do you do about the record button? How do you stop/start recording? I'll probably order a Headplay in the near future, the way I'm getting obsessed with them Thanks!
