Yeah, it is plenty stupid. I have read many people complaining the same, but to no avail. You can also add the lack of reliability to the drawbacks (more hardware, more software involved). I am fond of thumb trackballs, and the M570 I was forced to buy did not last very long ('forced' because I did not want wireless). It stopped working after a while, without any visible sign of damage on any component. Whereas my much older Trackman Wheel (the same as M570, but wired) is still my daily driver after more than 10 years.
