I use my sporty's E6B all the time, not so much for navigation but for
W&B, and Density Altitude calculations.

Once I bought a plane that couldn't be loaded outside of CG limits (when
carrying people, not pianos, anyway), and with enough power to take off on
even the hottest, highest days, I ceased needing to know that stuff.

We've got a beautiful metal E6B in the lobby of our aviation-themed hotel,
and it's fun to show to visiting pilots. Most of them scratch their heads
and say something like "Wow, I haven't seen one of these in years!"
