Theoretically, I think that touch screens and audio software could be a good match.
I've got Auria on the iPad, and I think it's a great audio-only DAW. Being able to magnify audio tracks with your fingers and draw automation seems like an intuitive thing to do.
As Peter notes, however, there's certainly a difference between something you can easily cradle in your grasp like an iPad, and having a 27" 2550 x 1440 monitor propped up on your desk.
And I agree with everyone on the thread, we'd need to see how well these drivers work-how is the speed, the multi-touch, etc. Also, I'd have to worry about how future updates to Logic might break these drivers; I'd feel better if touch support was "baked" into Logic, and not a hack.
FWIW, SONAR supports Touch, and it's gotten mixed user reviews. Some folks think it's the future, others think it's a pointless "candy." Having never used touch on a major DAW, I really don't know. But as I said, I think that touch and audio production could work well together, with a combination of using a mouse and keyboard with your fingers for specific tasks. But that's my untested hunch.
