ePaper display alternative

[joakim]

While not for everybody, I think it makes sense to also provide an ePaper alternative. It's a good fit for a low-powered device like this.

Some questions:

1. Are there any ePaper displays with the right specs (size, touch, refresh rate, etc)? Finding a suitable display probably requires some experimentation.
2. How difficult would it be to support? The hardware is one thing, another is software. ePaper devices typically use a custom UI. Maybe this should be a sub-project of SPIRIT, to facilitate coordination of hardware and software changes of an ePaper alternative?

Some benefits:

• Extremely low power consumption
• Excellent readability in sunlight
• Doubles as an eReader
• Prevents screen addiction (very low level of dopamine hits from ePaper)

Previous art:

• Light Phone II
• Mudita
• Hisense A9
• Boox Palma (not a phone, more like a mini tablet)
• Bigme Hibreak
• Minimal Phone

PS. I'm very excited about SPIRIT, and hope it succeeds!
