Trivia can be important

[Angus]

I recently planned to get rid of the advocatus diaboli image I fear I got by complaining and begging for features too much - but consider the primarily targeted market: a 16 year old might have well functioning eyes plus he uses the calculator in a highly illuminated classroom, so the keys are not much of an issue....

There are several small drawbacks that keep myself from using the prime for daily work, but I keep on trying to get used to the prime. So far as a hobby. Given that some users on this forum are able to provide excellent information I hope that I will at least get along with it. There is so much potential!
Hopefully my problems with merging cas mode with hp39 sources and the built in variables are no result of intellectual problems arising from not beeing the targeted 16 year old but a 40 year old donkey We will see.
