LEGO Education covers new Touch Sensor - some thoughts

Click here to read LEGO Education NXT's little blurb about the Touch Sensor. It mentions that a hole for an axle has been provided (see picture). I'd also like to add something that wasn't mentioned... the old RCX touch sensor had the toggle running along one axis ONLY (for example, left to right or West to East). This new sensor has two axis to monitor - up/down and left/right. I think this will greatly increase the sensitivity of the sensor. Combine this with the axle hole and the touch sensor will be able to more quickly react to obstacles and touch input.
