HP Prime or HP 50g

[edryer]

I liked the TI-89 Titanium however the LCD screen was too small and the fonts unchangeable. Also of course no RPN. It was built superbly. And with the cover still smaller than the HP-50G.

Thread creep a little but the finest calculator TI ever made in my opinion was the TI-86. I recall (I am sure) it actually had a few more math/stats functions than the TI-89/TI-89 Titanium. It was and remains a superb non CAS AOS Calculator, probably the best.

I stupidly gave it to a thrift shop a while back whilst having a clean out... and it was as new with a limited edition blue translucent cover... oh well.

HP-50G vs Prime... well I prefer the 50G but I suspect most of the target audience (teaching/studying folk) will prefer the Prime. Can't imagine most learning RPN or more unlikely programming in RPL.
