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.
