The advantage of e-ink, at least during the day, is that it relies on external light and so isn't particularly susceptible to glare. Another advantage is that it does not use any electricity except for when it changes. Not a little, but ZERO. So battery life is generally fantastic on e-ink devices.
But, I can't stand e-Ink for aviation. I always wanted something to do approach plates - Just plates - before the iPad came out, and everything back then was e-ink based. But none of the displays were big or high resolution enough to get an entire approach plate up at once in a legible size, and e-ink is so slow to update that I felt like it wasn't workable. Want to know what your minimums are? Tap on the mins to zoom in, and wait... wait... wait... wait... It took several (6-7?) seconds to update. Sorry, I'm tryin' to fly a plane here, I can't wait that long.
Umm... Add it to your firewall? You're gonna have to do that at some point anyway, right?
It's been somewhat painful to switch everything from USB-A, Lightning, and other "2000 and 2010s" connectors over the past few years. I'm only a little glad that USB-C is taking over, though - The physical connector has been standardized, but just because the cable fits doesn't mean it's gonna work.
Want to plug in that monitor? Well, that's Thunderbolt 3, not USB. Gotta have the right cable.
Want to plug in your laptop to charge? Well, that cable doesn't support full USB-C PD, so you might get a little charge, or even slowly discharge. Gotta have the right cable.
I've even heard that using the wrong cable can *OVER*charge some devices and damage their batteries.
So, while I'm all for standardization, it's gotta be more than just the physical plug.
