I personally use the HP Prime as a toy where I can play around with giac CAS. I find the language quite interesting and it can be addictive sometimes, like lisp but with many math features. I sometimes find myself playing with it just like I'd do with games or social media on my phone sometimes leaving it on my nightstand or taking it to the toilet lol. The keyboard layout is horrible but... Debugging is practically non existent on my hardware, it crashes as soon as I call the debug function.

About using it on bed time (nightstand) I think it could be bad because LCD blue light: it may disrupt your near sleeping time. And worse, I suppose you can't adjust colour temperature as you can do on some smartphones and computers.

And not only on night: when I am reading about maths I prefer non distracting devices and not backlight displays: I prefer to use paper and monochrome LCD calculators or e-ink devices to read electronic documents.

I use my HP 48 and 50g for daily use and also to play around as you do. I am thinking on getting HP Prime but light emitting colour colour could annoy to me. So I don't know if, after getting HP Prime, I would continue using my 48/50g more than Prime.

In that sense I prefer no backlight monochrome LCD or e-ink (although I don't know about scientific programmable calculator with e-ink display). I find HP 48/50 relaxing on that aspect, compared to light-emitting displays on computers/smartphones and modern colour calculators.

About keyboard: is HP Prime keyboard layout worse compared to HP 48 or 50g? I am so used to 48 that I can type fast and naturally on it. It may be Prime isn't so designed to program on it, but more to program on PC.
