I'm probably gonna sound like a broken record in this thread but the Pebble never used e-ink, it used a MIP LCD, and MIP never went away. Lots of sports watches use the exact same display technology from the exact same supplier (Sharp) to this day.
I was positive that some of the hype and/or marketing around it called e-ink but it looks like either my recollection is bad, or the hype was wrong.
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.
I thought it was called transflective : for transmittive + reflective ?
MIP refers to the displays ability to retain the last frame indefinitely, unlike typical LCDs which need an external controller to refresh them constantly, even if every frame is identical to the last one.
