Pebble were always careful to use the generic term "e-paper", which some people assumed to be the same thing as e-ink, but it's a different technology. Besides, e-ink is actually a trademark so they couldn't call it that anyway. E-inks claim to fame is using zero power when static, but it has very sluggish pixel response times, while MIP LCDs use very little (but not zero) power when static and have fast pixel response times when dynamic.
