JohnMy view is the hardware we use to input data (MIDI) and control Sonar wont be replaced by touch only enhanced by it.
Absolutely John, I think that's partly why a lot of people are very cynical about windows 8 and the whole touch screen thing as they don't see it as being practical and it's more of a toy for kids.
But as people have suggested here, velocity sensitive touch screens are something microsoft (and I'm sure lots of other companies) are working on so it wasn't just a whimsical fantasy on my part

I noticed in the two videos I posted someone was playing a piano/keyboard and was wandering if it was a velocity sensitive screen. Surely it would still use midi anyway ? The tapping on the touch screen would send midi data to what ever software was being used ?
The big question for me would be, how sensitive can they be made ? What I mean is some those platinum sample kits that I have for BFD2 have up to 256 velocity layers, I'd be interested to hear from owners of drum pads how many velocity layers they have.
Or does it not work that way ?
