I use an Anywhere MX too, my main issue with it is the loose ratcheting on the mouse wheel, the tiniest bit of pressure will move it and the ratchet mechanism feels quite mushy. From what I hear, you can change the sensitivity of it, but A) only in their software (which doesnt run on Linux) and B) it's not stored on the mouse itself (which means I can't just change it on my Mac and then move back to Linux). I think I have the Anywhere 3, maybe the 2S is better.
