35S Insanity

[Johnh]

Operationaly, I reckon the 35s is great. It has a good range of functions and everything you need in a non-graphic calc, a good enough Alpha mode to help with inputs and outputs, plenty of storage its easy to program and it has a worthy HP-quality keyboard.

But it has too many quirks and glitches which combine together to make it untenable except for the simplest uses because it is inevitable that at irregular and too-frequent Intervals and for several unpredictable reasons, it will lose everything and there is no way to back-up or recover short of button pressing.
