Best calculator for the working engineer

[Jlouis]

I have this 30th anniversary 12c and it's fast and although I don't like fast machines (the "thinking" running or flickering numbers are a delight to me), I liked the idea of a faster solver to play with.

This is Saturday night here, the children are with their aunt, my wife already ordered pizza....
Hmmmm I don't know....I think I''ll try Valentin's 12c solver....too old to rock'roll, too young to die...
