This is something I've given a lot of thought about in the past few months. I almost bought one of these palm phones but ultimately the drawbacks mentioned here and on reviews sort of dissuaded me from getting one. Your smart pocket watch reminds me of the runcible, which was really cool and I wish I had gotten one but didn't have the funds at the time. https://www.indiegogo.com/projects/runcible-circular-open-so...
