My quite ridiculous watch experiment above turned out to be kind of practical, but ultimately looked amazingly silly. However, the idea of a traditional watch with some smart functions around the band has some merit and so the Kairos T-Band suddenly makes a lot more sense than before because it may ease the way for some into the world of smart watches.
I now have an Apple Watch arriving on Wednesday so it will be interesting to see what the experience is like. Part of me is expecting to hate the interruptions and the attention it draws from people, but another part of me is curious as to how well it deals with outgoing messages etc. For me, the Pebble feels far too much like a one-way device, at least on an iPhone, to be useful.
