The 50G, this wonder...

[Tugdual]

No specific topic here, just a quick testimony...
I keep being surprised by the 50g. Basically whatever topic I touch I find a usage for it. I was recently developing a booking software and found myself heavily working on dates. While checking the software, I found that the 50g had this incredible Time menu with # of days between two dates or calculating the date after a certain number of days. Do you know many calculators with this feature ? - all right coding a Julian calendar might not be that difficult but still... features are there. Add to this the great menu + function keys and again you see that the 50g is not only powerful but also easy and quick to use. I keep being impressed by this calculator that has a use in so many occasions. Despite its indecent size I keep carrying it with me and you'll often find it on my desk.
Open question: does any other calc, any brand, compete with that one?
