So, how do these two input devices work with the tablet? Well, without going into too much detail, it's all about electromagnetic resonance technology where the transmission and reception of radio waves between input device and tablet offer both a means of generating power (through resonant coupling) and communicating information. Put simply, a grid of wires under the tablet's 127.6mm x 92.8mm active area is actually powering the pen and listening for its position, as well as receiving information from the pens in-built pressure circuitry."
I used to have a Wacom with the old Apple ADB serial interface and boy have they changed. Anyone here at Digital Media Thoughts use a tablet and if so which one?
