I have an ELO 19" full screen Resistive touch monitor. (same kind used in the Neko Open Synth) 1. it has a very good picture, 2 though it only has one touch point, it is AWESOME for tweaking synths, faders, etc. I find it to be very accurate on most DAW applications. However on Sonars faders it sucks ass!
But for modulating VST's though it's not multi touch, is so F*ken Kool!!!!
Set Automation to read, and for example I can record all movements made vectoring the Legacy Wavestations Vector joystick. I don't miss the multi touch as I have enough controllers, and when you just want to record movements w/o having to worry about assigning something, it can not be beat! Besides I like having the other hand free for working w/ physical controls, or keys. Also on many of Reaktors more esoteric ensembles some serious fun can be had, I mean FUN!!
Cheers!
