Don't go with the 960's then, go with the smaller flatter ones 530s?
550s?  or something like that, check batterybarn.  You will pay more
for the same watts, but you will get the flatter distributed weight
that you want.

Perhaps, but the reason the Sony's exist is not for wearables but for
the camcorder market, we are just leaching off of that.  Until we can
be placing orders in the thousands I doubt we will get a better bang for
the buck than the Sonys (thick or thin ones).

I would definalty want one, but I would hope I could afford it.  I
have recently seen some devices by TI that I hope will allow "on
board" charging, lets see if it becomes real.  As Li-ion become the
default rechargable battery I think/hope we will see on board charging
happen.
