I don't see the viability at that cost. Most hardware surfaces can be had near or below that cost and do the same thing. Why pay more for the same thing? In essence all they have done is take a DAW surface and put into a touch screen interface. The idea is cool, but I don't see it yet. It is a recreation of the wheel, not better, but equal at the moment.
There are 2 versions, the MTX and the MTi. The MTX is meant to compete with Avid Icon and Euphonix System 5 type products. The MTi is MUCH more affordable, with similar feature set but a smaller screen.
