After a bit of a surreal experience with the first 8800, and after a couple hours dealing with my rep and corp store, my replacement has a very typical rollerball. I was advised that what I first received was not a production unit and that it should not have been inventoried. Some district guy was supposed to be in the vicinity the end of next week for meetings and would take care of 'internal matters', but that's their problem.
With that being said, what I had with the first unit was (for lack of a better way to describe) a ball with a nub on it for directional control. The nub limited the amount of movement the ball could make, and as I described earlier, the on-screen menu would continue to move in the direction of the pressure I would apply/hold to the nub, and only stop when either I stopped applying pressure or the menu selections ended in the direction I was aiming, just like a joystick's action. Weird stuff, but I guess I'm now back to just being another bourjois 8800 owner.
I'm not sure I like the rollerball as much as the nub so far after getting this one setup and my data moved [alot of scrolling to get around], but it's growing on me after adjusting its movement speed a little.
