Hi Dave,
I've got the 27" Planar model (20 touch-points) that Cakewalk used in their videos.
Works great! But there are a couple of things you should know.
If you want to use Multiple touch points, you have to run Windows 8.
Right now, Sonar X2 is the only DAW app that supports multiple touch points.
In a multi-monitor setup, the touch-screen monitor *has* to be monitor number 1.
If it's number 2, 3, or 4 (and you try to put the console view on it as a secondary display), when you touch... it'll affect what's on monitor number 1.
