SwissMicros Announces DM41X Launch

[Johnh]

The SwissMicros range seems quite wide now, and they all seem enhanced relative to their respective Hp models I'd like to buy one, for engineering use rather than for collection. Which would you advise? based on:

Really clear display, two lines would be enough with a preference for larger characters with great contrast rather than very fine text. I consider my hp15c-ce to have a good display clarity, better than my hp35S though there's no alpha characters. I have an Hp39gii and can't read it at all.

Alphanumerics for reading program lines and setting up text prompts in software.

Input and output interface to pc, for storage and backup. USB C preferred, but USB b is ok.

Great tactile-feeling buttons

Basic scientific functions with solve, complex numbers and integration.

Any advice?
