Transflective LCD, ie pixel Qi.. look vastly more difficult to see in sunlight; https://www.youtube.com/watch?v=5UEqd-AnGeI
The company also doesn't exist and only produced 10" 1024x600 screens, which are barely usable. If you know of another usable product, or have anything to back up your claims, please do share.

To put it simply: ask people who have the Pebble. Most of them incorrectly believe it is an eInk screen, but it is a reflective LCD.
I also have the Metawatch. These are purely reflective, not transflective. They boast whopping 20:1 contrast ratios -- https://www.sharpsma.com/products?sharpCategory=Memory%20LCD... . Even at its best days (carta) eInk didn't reach that 15:1 https://wiki.mobileread.com/wiki/E_Ink_Carta , and nowadays it's more like 10:1.
eInk's primary advantages are power (and only if your idle period is long enough; if you have to update it with any frequence you're going to lose pretty soon to a memory LCD); and angles/polarity (specially compared to LCD), which some people also claim produces less headaches.
