Just bought a Mac Mini today and got it working with the 700M. Will post pics tomorrow on RainyDayGarage. The touchscreen is also working fine after the 25 point registration...no problem with the driver installation.
However... I did install the driver without plugging in the USB cable from the screen...when I didn't see the device detected, I plugged in the cable an it showed up right away.
We also did a customized Tiger install (no printer drivers, no other languages). Basically as minimal as we could make it.
