I understand and share the excitement over the upcoming Pebble [2] and the welcome attitude toward less satisfying smartwatches in the market. However, the only downside is that the setup is backwards: you essentially never leave your wristwatch at home, but on many occasions you may feel like leaving your phone. It would be great if the SIM card belonged in your phone, and could tether from there as needed. Yes, most of the time you will have your phone/phablet/tablet with you, and probably a WiFi connection, for that matter.

The closest device I have come across is the VEGA (-Z1) watch [3], which is downright ugly, quite pricey ($425), only offers USB tethering with poor support [4], all of this under an old version of Android. (This would arguably be the least significant point.)

I think the greatest usage barrier to this is the idea of using your phone for conversations, while all your shiny phones become tablets (unless you want two lines...).

OK, that's my proposal. What do you people think? Will this be the standard setup within 10 years?

Cheers!
