I've got 6 usable HP calculators (5 of them with LED's). I rotate them so all get used as my "Go To" machine, but remove the batteries from them when they are not being used. For the last few months, my main one is the HP-80 and I do currently have an HP-35 fired up as a backup. Being retired, my day to day calculating needs are quite simple.

I do have all of Cuvee's HP simulators on my phone, and sometimes I use one to figure a tip in a restaurant.

There are other times I really get into writing programs for them, but I've been distracted lately.
