One more question.  The apple specs show maximum operating = altitude of 10,000 feet.  If there is a good technical reason for this= , it would seem rather limiting for our en-route use.  The operat= ing temperature is also kind of pushing the upper limit when on the ground&= nbsp;on hot summer days.  The temperature issue can be somewhat contro= lled, but the altitude exposure not so much.  Is this a CYA or other g= eneric limit?
