Im guessing the potentiometer is Type "T" / IE smooth as H.
but still Wow, that's a price tag.

Just had to laugh sooo hard reading the replies

Brings a new meaning to the phrases playing with your knob.
 

KoooOOOoll,, I was looking for a rather simple way to over complicate using the boring old mouse and screw up my workflow! Damn the expense, I'm getting sick of this cheap crap anyway and would be willing to pay 3x as much if they install a really, really big vacuum tube, rough it up a bit for that vintage "custom shop" effect and assure me that it will definitely NOT work as described with Pro Tools.. That should be fairly easy 'cause very few things ever do for long.
 Of course, as a rule I typically work in SONAR and although I do in fact have a Mac running Pro Tools in my studio, I personally usually give that puppy a wide birth and don't use it unless absolutely necessary (upon client insistence. '-p)
 Clients could come in and gaze upon my wondrous Nob and ask; "Oh GEEPERS Steev, what does THIS Nob do?" and I could raise an eyebrow, shoot them a sinister look and reply; "DON'T TOUCH IT! It's very expensive."
 I do believe this extra Nob would fit in perfect with my extremely over priced Pro Tools rig which I try so painstakingly try to avoid using for anything other then running Reason..
 Hee, hee, how COSMIC, just thinking about getting one of these Nobs makes me want to go and punch my mother in the mouth for having me...
 Last time I felt like that was when I upgraded OSx and my Digi 002 Rack turned into a paper weight.
 Well of course I could have shelled out a $200 (US) ransom to Digidesign for new drivers, but I thought it would be more fun to shell out 3x as much for an Avid M-Box Pro, which in reality is exactly the same as an M Audio M Box, but with a really cool AVID Logo stenciled in purple on the top which is well worth the extra hundred or so dollars then the cheap old M Audio version.

ROTFLMAO!!

Still want one 
And might get one eventually..
 

On a more serious note I could actually see the Nob as possibly an indispensable and relatively inexpensive controller for video editing work in NLE's such as Sony Vegas Pro. Vegas does support MCU protocol which is OK for audio tracks but abysmally non existent for video tracks, and there isn't any video editing mixing/controller anywhere near this price range to my knowledge a novice could afford.
 
 And it should also be very useful to provide automation for plugins that don't support automation.
