Received my new HP 20B today. Summary: very disappointed. In the hopes of saving a few others time and money, here are my comments.
If you want a powerful platform to experiment programming firmware, I'm sure it's great. And it's always wonderful to see a new HP _RPN_ calculator. And yes, the HP 20B is pleasing at first sight with its:
- bevelled key faces, to allow for a 2nd set of key labels;
- double-width Enter (aka Input) key;
- raised edge, to allow safe, face-down placement; and
- high-contrast, easy-to read, segmented, number display.
But the moment I press a key - yech!! There's no 'HP click'. Instead only 'mush'. And to add insult to injury, I have to watch the display to ensure each keypress is registered. To be sure, this is not much different than any other non-HP calculator, such as my Sharp EL-733A Financial calculator. But it's the cognitive dissonance. On the other calculators I expect 'mush'. But when I see the famous HP bevel keys on the HP 20B, a lifetime of experience has me expecting the hinged-key 'click'. Instead on the HP 20B there's only 'mush'.
And yes, the HP 20B is a financial calculator _with_ the added bonus of scientific functions -- but they're mostly behind a single Math key. And this menuing system is more convoluted than that of the HP 17BII or HP 42S, with their labeled softkeys.
I mail-ordered the HP 20B, and so returning it is not worth it. But life is too short to reach for the HP 20B regularly, and then be continually re-disappointed with each key press. So for every day use, I'll stick with my HP 17BII silver.
