I got in on the Kickstarter (backer 1,000 something or so) and it feels like I've waited an eternity.
Yaz for what it's worth at their CES presentation they mentioned there will be multiple font size modes, so you can boost text size across apps easily, and there will be a bunch of different watch faces available (some of which will be easier on the eyes than others I'm sure).
The one thing i've wondered is how it works when it goes out of range of my phone and/or my phone dies. Obviously a lot of functionality would be curtailed at that point. So I guess that means I need to keep my phone with me around the house, which I'm not in love with.
The killer app I'm hoping for with it is to turn it into a Fitbit-like pedometer and sleep tracker. Apparently it has the sensitivity in the accelometer to pull it off. A lot of potential there.
