50g

When I first got my 50g, I thought what the heck is this thing want to
do with my mind????? As I spent time to learn the Ins and Outs of this
fine product, I have come to the conclusion that most of the
calculators made are equivalent to a San Francisco Tolley, always on a
reliable set of rails but do not try going where there are no rails.
The 50g will get you to places that others can not.
