I would (also) agree. A quick look at the handy product page that iFixit linked to (http://www.atmel.com/devices/atuc256l3u.aspx http://www.atmel.com/devices/atuc256l3u.aspx) shows that the controller has "25 touch channels", as well as supporting Atmel's "QTouch Acquisition" in hardware. As microcontrollers go, it's pretty beefy and would have made a decent computer all by itself not too many years ago. It's a 32-bit CPU running at 50 MHz, sporting 256 KB of flash memory and 32 KB of SRAM. Granted, it's a bit low on memory for a general-purpose computer. Maybe 20 years ago, then. :) It sure has a lot of I/O and other nice peripherals, though.
