I would love all my displays to be e-ink, meaning: My 24inch displays for programming, my phones, everything. Android would need to provide an e-ink mode, but that shouldn't be too hard to do. I honestly don't need that much animation or color, so I would be more than fine with switching to it completely. I can still use my old display if I ever really want to do some multimedia use, but for day to day use e-ink should be perfect.
