I think this is more a "wait and see" sort of event than a "writing on the wall" sort of event. Remember that the Touchpad was initially developed running Android. Furthermore, and as the other Amiga users here can attest, all or most of the next-gen Amiga platforms came through the hardware development phase running Linux before AmigaOS was ported over. This might be a similar situation - Android Linux probably has the widest hardware/driver support of any mobile OS, so it's a good test pilot for new mobile hardware.
