I'd totally agree. I abandoned my hp35s for anything more than simple calcs , despite its really good basic configuration and feature set, because the combination of a few too many design problems make it impossible to rely on. The main issues were.:
Too many ways that it can get locked up, or run out of power and so lose all memory
Battery warning not reliable, so it loses power before you know
Fairly short battery life
No input output for restoring contents
Check-sums are inconsistent, so no use for checking re-entered programs

If only there was some input-output option, and one or two of the others fixed, it would have been great.

There are probably production or design reasons why it can't be updated, but one of that scope, like an updated 42s, would be great. Other than that, there's SwissMicros
