I'm looking forward
To my wrist computer, programmable with Gps, phone, everything on my smart phone except for a large display. No bigger than a normal watch either. The trouble is for the outdoor sports I do both are going to need to be virtually indestructible because they'll get treated just as badly as a cheap digital watch,, but will be rather less disposable.
Think the tech is getting in sight now, but it's a big ask on the physical side. Having a waterproof phone I can take on a boat has been a happy step, but I think the wrist comp will need another level of miniaturisation.
