Desperately poking at a greasy screen seems counter to the ideal of making music while connecting with your inner muse.
Multi-touch is not a replacement for a mouse/keyboard...
But it is intuitive (for some things like zooming/scrolling)... especially after using a smart phone for a good while.
FWIW, just like with smart phones, if your finger is a bit sweaty (perspiration), it can affect the performance of the touch-screen.
I've got the same 27" Planar monitor here... and it works pretty well.
Couple of important things with multi-touch:
- You have to run Win8
- X2 is the only app that currently supports multi-touch
- If you use multiple monitors, the touch monitor has to be the main (1st) display
