HP 48G - what next?

[BartDB]

Hi,

Having used the 28 & 48 series of calculators myself, I would say go for a 50g. Unfortunately they are out of production now, so are getting quite expensive.

The Prime does have an RPN entry mode, but does not have RPL and the programs cannot interact with the stack.
The programming language is ALGOL-like and more suited for QWERTY keyboard entry than on-calculator programming.
It does have many functions, but the interface is more reminiscent of Casio calculators with various apps.
