Thank you for your consultation about the HP50g. It is one of the best calculators i have ever seen, especially after finding out the keytime command...
It beats the ti89(I own the normal version - not the platinum) by far!
The fever got me now - my father warned me...
Thanks folks
PS: My father needs a new calc. He is used to the 35, 41cv and some newer(90's) models(He always tells me about the 35 and the 41cv about the keys and the solid body) . Is the 35s a choice for him? I want to give him one for xmas.
