HP Prime or HP 50g

RE: HP Prime or HP 50g
My own 2 cents.
You mention that you currently have an Hp 35s. That is an RPN system and NOT RPL. The Hp 50G is an RPL platform. What that really means is that both the Hp 50G and the Hp Prime are both going to be new to you. While the Hp 50G may be more familiar to you, the actual usability of either machine in RPN mode will be new to you with the unlimited stack. The really nice features of the Hp 50g will be unknown to you and the easier to use Hp Prime might actually appeal to you more. The Hp Prime's RPN mode is usable and the stuff you don't have, you won't miss (because you haven't had an Hp 48/50g earlier model). A concrete example. Units conversions. Even the Hp 50G out of the box sucks at units conversion...... Until you enter RPN mode and set flag 117!!! Then it becomes one of the best calculators for units conversions made, far excelling the Ti89 for this feature. The Hp Prime, well, it seems like they copied the Ti89 in their convoluted way of doing units conversions. Your Hp 35s, only 6 units conversions so anything is a step up!!!! As Tim stated, the Hp 50G is the end of a mature product, starting out as the Hp 28c. Still has bugs, but nearly all of the warts are known! It is at its heart an RPN machine but with a Algebraic mode tossed on to keep it viable as an alternative to the Ti calculators. I suspect that Hp 50G algebraic users outnumber Hp 50G RPN users at least 21. We are just a small but vocal minority. The Hp Prime is an algebraic FIRST calculator with an RPN user option. It has adopted a Casio type interface and seems very user friendly to the initial user. That is probably not an accident. Hp wants the user to buy this calculator after only a few minutes of playing with it. And it does have an excellent look and feel. If I did not know the Hp 50g so well, and was getting something to augment my Hp 35s, I would most likely buy the Hp Prime and never know what I missed. The Hp Prime is an excellent tool/toy. And truthfully, you should buy it. But I would also suggest you bargain hunt for an Hp 50G too. They can be had for half of the cost of an Hp Prime. If I had to take a high end number crunching physics class, the Hp 50G would have what I needed NOW, where the Hp Prime may be lacking in some critical areas, especially if you insist on driving it in RPN mode.
