Wrist?
I stopped wearing a watch years ago (my phone was a more accurate and useful device) so I need something pretty useful to make me want anything on my wrist.
I had a pebble for a while, I liked the ease of glancing at notifications, but that also made them more intrusive (even when driving it was tempting to just twist the wrist a bit).
I have to look at them and consider them a solution without a problem for most cases (kind of neat HR monitor, but really???)
