First, "pocket" refers to the size, not the method of carrying. Carrying one in a shirt pocket is inviting disaster when you bend down like to access a lower file-cabinet drawer and dump the expensive computer out onto the hard floor. Carrying one in a pants pocket puts it in danger of breaking it, something which happened to a friend of mine when he sat down hard. Fortunately it was a much cheaper model.

The 41cx manual calls it a computer, which seems reasonable since it has string-handling capability, a file system, and text editor, and with HP-IL it has the ability to interface to lots of things at once (not just consumer things like printer and mass storage, but lab instrumentation), and with other modules it has boolean functions, base conversions, an assembler, and a mile-long list of other things not found in mere programmable calculators.
