There are 2 e-ink screens with flex connections (these are pricey connections). It looks like it was made to be reprogrammed and different screens...
I think someone out there will likely reflash the PIC and make the segments go on / off at different time and perhaps put other displays on it, there's a little bit of hacking to be had but not that much really.
And here's my opinion, I know a lot media folks & tech sites are pooping on this cover - but someone needed to start somewhere, I'm glad there's an E-Ink cover in existence, it's clear it's going to be decades until it's something that very common.
I can't wait to see some of the first hacks of the Esquire cover to start rolling out.
