Top three calculators ?

[Marcel Samek]

1) HP-67. It's on my desk at home and unless there is a reason not to, I will always gravitate towards it. Love the red LEDs especially because the lighting in my home office is usually dim. There is a definite pleasure in using it - much like using my old Leica cameras or a fine fountain pen - neither too practical, but an irrational joy to use.

2) HP-15c. From a feature and layout standpoint, this is probably the ideal calculator for me. For more complex tasks it is invariably what I reach for. Just the right balance of depth and ease of use. I use the LE but I don't think that's really relevant. If I could get a 15c with a red LED display (or better yet Nixies!) would never look at any other calculator again.

3) Tough to pick one to finish off this list. At this point I have probably spent more time with the WP34s than any other calculator and I like it conceptually, but the buttons of the base calculator are lousy and I get frustrated with always having to reach for the reference manual. I might have to choose the 35s - the ergonomics are good, the build is decent, I like the feature set, and unlike all my copies of the 32sii, it just works.
