Would love to but damn. Last time I check the price of an 13-in eink, it was datsun something and it was $800. And it is just HDMI anyway.
For other eink device, I would wish for mainline support of the SoC first before anything else. Those non-HDMI e-ink always driven by a crapstatic SoC anyway.
I wait for Bottles to have it but yea)
