Pauly, while I agree with you that there are very well implemented suspended tables I think you have overstated a few things to make your point.
The platter is directly coupled to the plinth via the bearing, unless the bearing is of the magnetic/air type. The plinth on suspended tables are not directly coupled to the stand, but rather floating on the suspension. If there is sufficient drag on the platter during dynamic passages there actually could be a rotational twisting reaction on the platter/bearing/plinth as well as the drive. I do believe most higher quality suspended designs have addressed this to the point where you would probably not hear it.
As for thumping a non-suspended table and making the cartridge fly, I can tell you that that is much easier and more likely to happen with a suspended table. That is exactly the reason I moved from suspended a (Basis) to non-suspended (Galibier) table. It is not the first moment of impact that caused the stylus to jump. It was the second moment when the suspension jerked back to the steady-state position that the stylus left the groove because it wanted to keep going in the original direction of motion. Bodies in motion tend to stay in motion unless. . . yada, yada.
We can all look around and find good and bad implementations of both approaches. I don't think it is so easy to dismiss either when the implementation is well done. I still have a high regard for Basis tables but there are some things I would never try to do with any suspended table. Like adjusting VTA and AS while the stylus is in the groove. I realize this isn't important for everyone but it was for me. Lucky for me that I'm in a position that I don't have to have a suspended table.
