I started with RPN in the 2nd grade when Dad would bring home the desktop size card readers from work (son of an engineer) in the mid 70s. I have been through an 11C (my favorite, 22 years old and still going like new. Only the second set of batteries), a 28S (all I need is a little more leverage?), and now use a 32S.
If I could find an emulator for the 11C, I may have to buy it.
