Re: Overstocked on PDA's

I have been happily using a 3760 iPAQ for two seasons now, with no 
display visibility problem. The only drawback is actually the poor 
autonomy on internal battery.

As I am flying club gliders, I am using a set of 4 D-size NiCd batteries 
(4400 mAh @ 4.8 V) which allows for something like 10 hours with a 
Navman 3000.
