As somebody who flies /A everyday, I'll say that it sucks in this day and age. Any pilot who chooses the more analog/old anything because he thinks it makes him more of a man is a poser. I haven't even used a goddamn E6B in 10 years (pre-private). Hell, my watch has an E6B bezel and I've completely forgotten how to use it because I can accomplish all of my major calculations with basic math. I have an older ASA (I think) electronic E6B, but I haven't used that in years because its usefulness to the working pilot is pretty negligible. E6Bs are the domain of student pilots, I reckon. If I really needed one, it would be in my flight bag.
