Part of my complaint about that is that although I think the different punctuation marks are great, using them is a pain because of keyboard layouts.

It's easy to find a hyphen (or something close enough) on your physical keyboard, but there's no em dash. OSes also make it a pain to automate even when they claim otherwise.

I go out of my way to use em dashes but do I think others would? No way. So is lack of use because of lack of utility or because of idiosyncrasies in keyboards?

Hyphens are great for some things but are too short to visually offset text.
