Even with almost all of my work done on a computer, with Python, MATLAB, etc. available in a few keypresses, I still keep a calculator on hand. I haven't come across a desktop calculator (including direct 1:1 software recreations of classic calculators) that's quite as user-friendly and efficient as grabbing a scientific calculator off my desk and typing in there.

There are just some user interface advantages for me in having a physical calculator. The only thing stopping me from buying this is the price tag.
