I had the 1st two generation Pebbles, and now I'm using a Versa Lite. I do find a lot of resemblance on Pebble. Granted it's not open at all and their 'store' is, to me, much less inviting. Yeah not open source at all.
However, I also recall that Pebble was looking into Android with their 'Pebble Core'.
I do miss their e-ink screen
It wasn't eink! But low-power transmissive LCD. Best of both worlds IMO, faster refresh rate and still super low power.
I was a backer of the original pebble too.. It's a shame things didn't work out. I think they just grew too quickly and got caught up in too much investment money wanting too quick returns.
