My ideal smartwatch would recharge itself from my body heat/movement, be waterproof, have a cell phone/wifi, and best of all be pay-as-you-go. 90% of the time I'd be on wifi so it would be free anyway like T-Mobile. GPS and bluetooth would be nice but not critical.

But just being able to never worry about forgetting it, or having to charge the dang thing, and be able to contact anyone anytime would be very sci fi. And of course the most important feature of all would have to be: disabling it easily to prevent interruption.

I see a day when devices won't need GPS when outside; access points/cell towers can have precision/differential GPS receivers and your device's location is calculated using RF signal strength/triangulation data (802.11ac already uses beam steering for better reception/throughput). I'm aware this is already done using CellID and signal strength data; I'm simply saying it'll become more accurate and widespread.

If you can offload the energy hungry tasks, these devices become much more realistic faster.

You want a wifi receiver and processor powered by a small amount of heat and movement? Don't really see that happening.
