Also any older folks who grew up with HP calculators and prefer RPN over the newer calculators.
There was a time when RPN was waaay better than the TI and other competition, but in my mind that time is now past us. I can use both designs well and will take a TI-89 over a Swiss Micros (mind you I own several) almost any day as it is more straightforward. That's my opinion anyway. This improvement over the DM42 is pretty cool though.
Another Swiss Micros use is for people who work in a lab with gloves and can use a calculator better than a phone.
