There are lots of reasons why satellite handsets are larger than cellular. The most important reason is that it takes more power to transmit a usable signal to a satellite than it does to a cellular tower. I don't remember what the real numbers are, and I believe the satellite can make do with a weaker signal. But the important piece of math here is the law of inverse squares, which says that if you double the distance, you cut your signal strength by a factor of four. If you triple the distance, the signal is diminished by a factor of nine. And so on. More power = bigger battery = bigger everything. I have no doubt, though, that some smart Qualcomm engineers (quite a few of them, actually) are working hard to bring us new models that will compete size-and-weight-wise to any cellular phone out there. Patience is called for, John.
