In the near Future someone( , or we) has to rewrite the Informations on Wikipedia:

The third, advantage of silicon is that it possesses a higher hole mobility compared to GaAs (500 versus 400 cm2V-1s-1).[10] This high mobility allows the fabrication of higher-speed P-channel field effect transistors, which are required for CMOS logic. Because they lack a fast CMOS structure, GaAs circuits must use logic styles which have much higher power consumption; this has made GaAs circuits less able to compete with silicon logic circuits.

This is (or should be) one of the major Improvements of the Research of Dr. Geoff T.

Maybeit's to early to edit this ? Do we have to wait for the official Release of Poet ?
