In my whole engineer's live so far I have never come close to the idea, entering matrices for transformations into a pocket calculator. What rules is a reliable keyboard for calculations up to square roots and linear interpolation, some conversion keys (inch, Fahrenheit, HMS) and that's it.

Sometimes I even use an HP 45 just for fun and to some interest of my colleagues.

For keyboard reason I would resist buying an HP 35s or an WP-34s, despite the fact, that both are nice machines in the right size. For same reason I rarely use a swissmicros 15L clone.

At the moment I have an HP16C and an HP41CX at my desk. For me climax of calculator keys developement. Second one is a bit dangerous cause of peripheral mania ;-)
