Must be the trees and wood, but for me, comparing SMS to Morse Code is an invalid comparison. They are entirely different in purpose and implementation.
SMS was not designed for speed. It is allocated to the Slow Access Channels (SACCH) when voice is active because it is deemed less important. Works as designed......they needed a study to figure this out? Why MC is no longer required is also a puzzle to me. Too much dependence on new-improved-murphy controlled technology.
I notice they kept the length to < 160 bytes to fit in one frame. Wonder how long it would take to write 65K worth of data (max SMS assembled message) and transmit that in MC? (and persistently retry transmission to the destination).

Um... yeah, you bet. (Did he answer my question, anyone?)
