reads interesting and is in sync with my ideas on future interface: small hand gestures with more options than mouse moves and different clicks.
In german online issue of "Der Spiegel" the controller was discussed - main points for me were:
- seems to put a high burden on CPU (no mention of used HW, guessing an i-type laptop CPU, not an Atom)
- rather inexpensive test set (my first fear when high resolution was mentioned)
- currently not enough software utilizing it
- goes into more dtail that mouse driven desktops are currently faster (where I am not certain it is only a calibrating/learning deficiency observed)

interesting development for sure
