I always think refresh rate and color aren't the problem, eink vendors need to find the right customer crowd.
For color e-ink displays, instead of competing with LCDs, target a niche market: 8-color terminals for programmers.

We always aimed at fixing the lag, be it terminal rendering performance, network jitter (mosh anyone?), proper tab completion (including the ones that require network responses to complete), TUIs...
I'd still use eink for terminal, if it was cheaper. Just saying refresh rate is important for terminals.
