You keep willfully missing the point, no-ones disagreeing with you that direct drive is better technology, Ive delt with industrial direct drives for years, its far better and yes, one day it will the the standard for top end mounts. No PE and perfect pointing are obvious advantages.
The point is, present technology can give exactly the end result you need, in short, round stars, so newer technology needs to be at least cheaper just to get a foothold in the market (and have all the other side factors mentioned, which only become provable over time in the market place). This is a difficult situation for ASA, because reliability, support, availability etc can only be proved with product in the market place, ...........chicken and egg. And they want to charge more!
There is not the same pressure now as when PMEs came out, the PME finally gave robotic operation to amatures, and well,........ round stars, always. The ASA DD will fundamentally give the same thing.......round stars, always (supposedly, they hope).
Pretty much the only better end result possible now (not talking about the technology at all), ie *smaller* round stars, as Peter says, is predictive guiding, and man, we are a long, long way from even getting close to how that would be done on an amature mount. AO BTW is still reactive.
