I felt the same way when I got the newer gray version. Was it the ball? It seemed a lot rougher and kinda grinded compared to the old model, for me.
I wonder if the one that just came out recently feels better.
I know a lot of trackballs from IBM have that sort of "click-lock" feature. It's very useful for playing Solitaire when you drag cards around.
