Unfortunately, I can not come up with a more eloquent reply to your statements.
I have been trying to find out what the DPI rate on the New Kensington Trackballs are compared to the older ones.
But I can't find DPI rates on either.
Thus, I can not tell if the newer trackball is an improvement, or just the same.
On the Third Party Mouse Software front......
Still looking......
