Just curious. I'm not an engineer and not trolling. Is there a reason why people are still using these instead of an app on the phone? I personally still use a Garmin gps, because some places I drive through I lose connection on my phone. So does this calculator serve a similar function in that kind of aspect?

School? Not sure if they still use these in hs and college but I used a non color screen one many years ago

Multiple college pre-req and college level class tests require them, and won't allow the usage of a smartphone due to cheating. They're essentially mandatory for a lot of High School and College students, like "on class supply list" mandatory.

Nobody thinks these are superior to a good phone app; but they aren't going away any time soon.

Not to mention some of us don't want our kids on the phone while doing homework.
Kind of a no brainer.

They are used for mathematics, physics, whatever. Most engineering courses don't actually allow them..
