I don't really care about the smartwatch, but the Mirasol display should really get more attention from other OEM's. It's probably the best compromise between e-ink like battery life, and having colorful animated screens (nowhere near the color richness of the latest IPS LCD's or AMOLED's though, but it seems good enough for something like a smartwatch).
That's why so far from all the smartwatches being announced out there, this one grabbed my attention. Though to be honest, I'm still disappointed in the design aesthetics.
