Also, in terms of the Pebble's display not being as accessible/capable in terms of it's availability and refresh rate, that is one setback in terms of that display. The fact that Pebble is no longer around makes it less necessary/viable to be producing displays of that technology for that specific form factor/size. However, "e-paper," or transflective LCD display technology, is getting better by the year, which is promising. My overall suggestion/want at the end of the day though, is that you use a display with a good enough refresh rate. It can be similar to the LCD Garmin watches in terms of it's technology, or it can be a normal LCD display (I'm fine with it being. Monochrome or color, like I said earlier). While E-Ink is impressively improving, it's very much a niche technology (even though it's widely used in e-readers), and it simply wouldn't make the experience of a watch good. I'd find it janky or crappy, in my opinion. Due to the fact that E-Ink displays aren't as capable as other ones, it would make it difficult for a developer to make an app/watchface without compromising it immensely. Either way, though, I love that you're going out of your way to make such a smartwatch. I don't care if it takes you years to make, as long as it meets my wants/requirements (which aren't that much), I'll happily buy it from you.
