I'd prefer to see Access get the hang of basic VST DAW integration fundamentals that seem to have escaped them so far, and until Kindergarten is graduated the big leagues might be a way off, but as a creative idea, tablets offer a lot of future with regard to touch.
Take a look at what Spectrasonic is doing with Omnisphere.

I do own Omnisphere, and it is a great plug-in, if not a bit on the CPU-heavy side. Its got a great sample library, and the ability to mix samples with synthesis in an amazing way.
