For every person like us that posts on these forums, there's probably hundreds that don't.
I'm sure most of those folks won't be interested in plugging their $999 keyboard into a $450 Vent. Don't get me wrong, I own a Vent and love it, and it will make any workstation organ much better but most of the buyers of this board won't spend the money on a Vent.
It just comes down to dollars and cents for most players that are weekend warriors, hobbyists, church players, etc. It won't matter to them about most of the concerns in this thread.
I think it's a pretty cool keyboard and I bet they'll sell a whole bunch of them.
