I have got a Mx Ergo, and to everyone else out there asking questions about this trackball. Let me tell you. As long as you are not using the mouse to draw (photoshop, gis software, cad software etc...) you will adapt. And the thingy is comfortable to use. If you need to do some of those tasks that requires drawing a polygon, snap vertex into other things etc... The MX Ergo is not for you. You can do it, but you will be significantly more slow, even after months of practice. Look something else. I wish someone would have told me this before.
