Just to remind everyone - you do not have to rely on the web page for configuration. Access the web site, save the page source to an HTML file and then use a MIDI-enabled browser to run it locally, thus insulating yourself from the company pulling the website or going out of business. On a Mac I believe the 2 options are Chrome and Opera.
While I love the simplicity, fader size/feel, small size and low cost of mine as a MIDI CC controller for VI's, I'm not sure it would be my first choice as a mixer/DAW control surface. A unit with some buttons, motorized faders and support for Mackie control protocol would make more sense IMHO. Of course that is also quite a bit more expensive.
