the difference between the free2 and pro2 is that the free2 has a open roller bar, and detacheable wrist pad, and more precision (dpi). It's also about $40 more expensive.

With this, you don't have to “move hand off keyboard” anymore, but am not sure it's better than mouse.

Depending on how much you type, moving hand off keyboard may be a good thing, because it provides your hand muscles a break.

One issue with this device is that you may get wrist pronation problem.
