Slightly embarrassed at two years of lurking on HN and the first post being critical of HP...

I've had two HP35s units and they are buggy as hell. Ended up with an old TI86 after trying every calculator in existence.

What kind of bugs were you seeing? I'm use it for EE so it's primarily trig ang log functions. I'll never use the advanced features, but I can't use anything but RPN.

Mainly complex values wrapping in the display, memory corruption and annoyingly, really poor trig accuracy.
