 yes.  and low-power as a result.  and low-cost.  only 441 pins, 0.8
BGA grid.  virtually all of those are multiplexed.

 yep.  low power equates to high latency.  realtime I/O directly
conflicts with that.  c'est la vie.

 yyep.  it takes far too much power.

 abbbsolutely nuts.  it's causing massive problems.  look up the
"BMorn" tablet for example.

 the ones we'll be doing, will make damn sure of it.
