One of the most important points: The 41 was a groundbreaking classic, the 42 is only tech.

41 years ago, the HP41 was the first alphanumeric mobile computer and started the age we consider normal today.

The most important point between the HP41C(V/X) am the HP42S was external storage. There was no way to save the programs of an HP42 on external memory. After a reset or a new purchase, all programs had to be re-entered via the keyboard. Therefore, the HP42s was never a real alternative for HP41 users.

The charm of a classic, the incomparable font, the buttons for + - * / on the left side in addition to the higher compatibility are reasons for a DM41X instead of a DM41L or DM42.
