Microsoft announced two new trackballs based on the same IntelliEye optical motion sensing technology found in its latest ball-less mouse. The two models share features such as mulitple programmable buttons and ergonomic design but give you a choice of ball placement, either side-mounted ball or top-mounted.

I had a chance to try the model with the top-mounted trackball. This new innovative trackball from Microsoft has a very nice feel. I have been a trackball user for over a decade ever since my first Focus trackball and my CH Products Rollermouse. In fact, I even use a trackball for image retouching in both Adobe Photoshop and PhotoDeluxe and a Memorex trackball on my testing bench. A trackball is easier to use since there is less arm movement.

This trackball had a live “effortless” feel, even though it was a pre-production prototype. Although I would prefer a larger ball, like the Rollermouse, this trackball's size is comparable to the Memorex trackball. I felt no flat spots that I felt in other models (such as the Focus), especially as they get dirty. Since this trackball uses Microsoft's "touchless" IntelliEye optical motion sensor instead of a mechanical system, dirt and other "ball gunk" won’t even be an issue.

Overall, I liked the experience and look forward to trying a production unit in the Fall when these will be available.
