From the descriptions on the website they claim it controls like a touchpad, not a trackpoint. (touchpad means tongue distance == cursor distance whereas trackpoint means tongue distance/pressure == cursor speed) That being said trackpoint-style movement sounds better to me since my tongue has such limited motion compared to a large trackpad surface. Unless it is about to be much more dexterous than my finger (which doesn't seem right to me, but impossible to say without trying) it would be annoying to make large movements and repeated large movements seems like it would be tiring quite quickly.
