I knew it!
Lightweight backpacking geeks are really closet calculator geeks, too!!
I have a 41CV with all the accessories, including tape reader (museum quality) and use daily my 17B II. But I find myself using an Iphone app, Fast Figures, more often, got to be able to triangulate those baselines out in the field, don't you know! (and read that latest novel, watch the latest movies and listen to my tunes.)
Ah, the joys of geekdom.
