Glad u didn't have to bail, @Hunka Hunka Burning Love! U might've had to perform some hillside Tesla panel re-popping a la @Marty Backe
And yes, after only a few days with a speaker I can agree it's addicting.. only thing is now I cant creep up on people, which I found sort of amusing... I just hold the speaker in one hand. I kind of wish it had a strap, but its surprisingly comfortable to hold anyway.
My theory on getting all wobbly when crouching down is the lower center of gravity, i.e. it's easier to balance a yardstick in the palm of your hand than a pencil.
I think wobbling happens because of unequal compensation.. never tried the foot trick, but I try to shift weight
