Watches are too small for modern communications technology right now. You can't get the RAM memory, CPU power, and storage into that small of a container.
Think of the 1950's to the 1970's movies with "futuristic" technology where they showed a watch. Ain't gonna happen quite yet.
However... what do people ALWAYS have with them?
- Mobile phone
- Wallet/purse (not relevant here, but true)
The technology **is** there to marry a watch to a mobile phone.
So why not use the watch like an old dummy terminal with the mobile phone as the server?
That gives you all the connectivity and processing power you want.
The problem then is mobile phone battery life. And the watch battery life because wireless communications and video take up a lot of power.
The problem of mobile phone battery life can be mitigated easily though through connecting to desktops/laptops, and using a cycle to check for other devices, e.g. connected tablet computers.
That space will be filled fairly shortly though. Give it 5 years or so. Maybe 10 at the outside.
What do you guys think? Should I start a kickstarter? Or am I only designing for myself?
You are not designing just for yourself. If done right... e.g. You get a call on your phone, answer it on your watch, and if it's a longer call you walk over to your phone & use that **seamlessly**. (The audio quality/volume will be paramount - you must have a good speaker that far exceeds the quality on a mobile phone.)
Can it be done? Absolutely.
Can you do it with a Kickstarter? Dunno. It requires a huge amount of investment into hardware and software development.
Batteries will be a problem though. Careful planning there is essential. e.g. You talked too long, but still need to tell the time, so a reserve is needed.)
