I saw it at NAMM, where Seth was demoing it. I can see it taking hold in a year or so. Ahead of the curve those Bakers are.
You've got to be running Win8 to take (full) advantage of the new touch features.
ie: No multi-touch without Win8
That puts some folks on the "bleeding edge".
I've got the 27" Planar model used in the Cakewalk videos (20 touch points)... and it is pretty cool/handy.
Note that touch isn't a complete mouse replacement... but it's very intuitive to use for zooming/scrolling/etc. Especially if you've used a smart-phone (and most of us probably have at this point).
I'll also say that touch makes using Win8 a *lot* nicer.
Once you've navigated Win8 with touch, you can see why certain things are the way they are (seem more tedious with a mouse - but are quick/easy with touch)
When I've got a moment, I'll take a snapshot or video of my setup.
Got two 27" monitors (vertically) on a studio desk.
BTW, If you're using a touch-screen monitor in a multi-monitor setup, the touch monitor *has* to be monitor 1. Otherwise, you'll touch/control monitor 1's content.
