I was devout HP-48 fan back in the day, even did some custom programming for one for a client (got paid!), deployed about 20 of them in to the field. This thing was a real delight to write programs for. Just RPL, nothing fancy. For $99 at the time, they were a handheld powerhouse.
My singular complaint about them today is the lack of a backlight. It's just plain hard for me to read now.
I do have one on my iPhone which slots right in to the "good enough" category, even though the tactile feedback of the keyboard is lacking. What it lacks there is more than made up in handiness and readability. My go to application for it is equation solving.
Haha. I missed the glory days of hp-48 (plus they never seemed very popular in Poland), but when I got my first android phone, pretty soon out of curiosity I installed Droid48...

Is that true for the earlier HP's too?

Oddly, even though I used 48's and still have a couple in a drawer, I've settled on an HP42S emulator. (This was a lower end, but still nice, HP that was more directly a successor to the 41. In some ways, it feels more direct and calcualtor-like than the 28/48/etc series)
