If you were the first to ever create a device

[Gizmo]

So for a moment imagine there was NO devices in the world, it was the old days. You had the idea to build a device and it would then turn into a million dollar selling product.

What device would this be? Could be anything. Could be a phone, could be a computer etc.

What would it look like? Remember it would be the first ever device - so no one cares how big or small it is.

How much would it cost?

Would this be a sole project or would you start a company?

Discuss here.
