In one way better range has definite positives: pair one's BT outdoor 
speaker with the music system inside the house -- maybe apartment as 800
feet is approximately eight stories.  Negative is more possibilities of 
someone snagging the device, more interference in the band because of 
the additional range.

Seems a timeout would make more sense: save battery power comes to mind 
(transmitting the "hello out there!" signal takes energy).

Wonder if it does a periodic check to see if the paired device is still
lin range?  ...As soon as I typed that thought that wouldn't make sense 
as the phone travels and might be out of range for several hours.   Of 
course could allowed to miss a few 'you out there?' checks...  Probably 
more once paired always paired.
