Seems fun to comment on these points, please don't mind
- A mobile wearable should not be a watch.
What happens when someone who wants to wear their ...
I believe you hit the nail on the head here! Very few people (that I know of) would wear two watches. Those who are wearing luxury watches probably won't even give a slight consideration for getting a smart watch (maybe for exercising? we've got smart health bands for that purpose).
Knowing your market is important though, who's going to spend $1,000 for a general computing device that is not a smartphone or a PC/Mac. Not that I know though.
2 The wearable should not be the accessory of a larger device but should be the core of an ecosystem.
Partially agreed (if I understood correctly), I would say it should be a smartphone replacement itself.
Cannot fully agree, if skeptical, if you mean it's the only device lay users ever need.
I'd say that's overly ambitious but rational.
3 Do not put a screen on it.
This is tricky. Any other display methods IMO doesn't really work, including pico projectors.
In fact, at some point I though the Google Glass solution, or visors, would have worked. If there was something that can project a reasonably sharp image to just about any consumer glasses, it's going work.
Now I'm thinking about AR and the technology Hololens used.
4 It must be water-resistant.
I'll take this for granted.
5 Battery life is everything and contactless wireless charging is a must.
I'll also take zero-interfacing as granted for such wearables.
Wearable accessory should not have any holes you plug stuff in.
Holes are necessary evils from the start, they accumulate dust, make things less water resistant and stuff...
I kind of understand why Apple is trying to push towards wireless-everything. Not that I like what they're doing it to a smartphone though.
6 Processing power, storage and RAM are your make or break specs.
I do not fully agree with this.
As a user, there are things you can and cannot do effectively and efficiently with a cannot-be-seen device, interface-less device.
I see that this compliments you 2nd point, if it means to be the One Device though.
I can picture that if someone has a Bluetooth keyboard at home, along with a supported smart TV, can flick a finger to connect everything together (we already have these technology) and the TV suddenly becomes a full PC wirelessly powered by the strap on your wrist.
This doesn't mean the users who would prefer doing this needs top-notch computing specs.
I believe professionals of different fields - graphical artists, designers, photographers, animators, etc. - those who need 16GB/(top-notch) 512GB SSDs, have strong preference on what device they work on.
Again, I'm not one of them so it's just my imagination.
7 Understanding your target price point is important.
Agreed. In fact in my opinion, utmost important point in terms of business.
8 Security is paramount.
Again, taking this for granted. Not much to say about it.
9 Design from the perspective of jewellery first, technology second.
Agreed. There's always a gap between Engineering perfection, Aesthetics and Usability though. Striking the balance between the three is difficult, doing it right alone would imply partial success of a product (or more accurately, doing it wrong alone would imply failure).
10 Support multiple Operating Systems.
Cool idea but hard to realize.
