Cool..good to know...and as I suspected they are pretty big. You would need 3 of them for 3-axis sensing and every cubic millimeter you devote to a new gadget is a cubic millimeter less battery volume.

Well, just because somebody wrote an article doesn't mean it's Providence or even a good idea...the fact that said gyroscopes DIDN'T come with smartphones as predicted should clue you in to that. As for the PS3...it has a gyroscope because they decided they wanted the ability to very precisely measure all 6 axes (it also has accelerometers) at additional cost. A better comparison is the original wii controller. which had accelerometers only (they were trying to keep costs down) and did an exceptionally good job for all but the most precise motion use cases due to the excellent software they wrote for the motion control. The $30 add-on brought gyroscopes to the table for more angular precision...but it *added* to the capabilities that were already there (and it does, in fact, occassionally get out of whack and requires resetting/recalibration) . The reverse would not be true (you couldn't have made a wii controller with just gyroscopes and added the accelerometers later).

So, now we get back to the phone world. Exactly what is it that you hope that your phone could do with a gyroscope that can not be accomplished with the already included accelerometer setup? Maybe I'm just not creative enough to dream up what it is that I'm missing out by only having lateral force sensing in my phone.
