IMHO, hardware with all those cool dials are all nice and dany hands on old-school technology (which I love) but that does not translate logically for today's ITB virtual recording studio (DAW)... {read on} especially as we move towards more advanced UI such as,
Touch -- think along the lines of the movie Minority Report.
Yes, just one big mother load of a screen with pip technology integrated

positioned on a flexible portable unit (frame) to allow me to adjust from flat-top (table mode) to straight-up vertical mode... the vertical mode is ideal for anyone who prefers to stand-up and wiggle their heinie all whilst they tweak and play with SONAR.

Hey, don't laugh, vertical mode (standing position) is actually a much healthier (physical) workflow / workout.
Virtual mixers such as Prop/head Record, hmmm, all those cute little tiny itsy bitsy dials? Arghhhhhhhh... sure that's fine if you have an awesome controller interface but why bother if as pointed out (Minority Report) is where the future is heading. Touch is here and it's going to get better and more affordable.
That and above said; in regards to the UI, it makes more sense to get rid of dials and replace them with commonsense / cleverly designed UI to make it way more user-friendly; both visually much clearer, graphically informative for example, pan, volume, filters and envelope parameters don't need no virtual hardware faux-asinine annoyances such as little dials, dang it, just point and swipe directly on the parameters and/or graph.... This in essence frees up a lot of valuable screen space to allow more room for clearer more informative UI feedback (details) and workflow. Developers have been almost locked into this 'modelling based on old hardware technology' all whilst wasting valuable work-space / screen-space as explained earlier.
