With the whole HP TouchPad fiasco going on, I was wondering something. Tablet PCs are so ubiquitous these days, and yet something like the Wacom Cintiq is still so ungodly expensive. I realize they can price it that way since Wacom has a de facto monopoly on good graphics tablets, but what are the chances that somebody will eventually make some competing device featuring a built-in LCD screen? I can't imagine the cost to build a Cintiq is anywhere near the cost to build an iPad2, and yet the Cintiq costs twice as much anyway.
