There is an ultra rare Airtangent straight line tracking arm that had the capability to raise and lower the arm by remote control. That would be close to the ultimate setup for lazy adjustability, particularly if the arm were a neutral balance arm where tracking force does not change (I don't know if that is the case).
The Basis Vector arm has a mechanism that would allow for on the fly raising and lowering of the tonearm, but, when one selects the desired height, the main locking grub screw has to be tightened, and then the raising and lowering mechanism is backed off so that it is no longer in contact with the armboard (too much work for ultra lazy people).
