where Bill and steve find ideas?

Here is an interesting finding where you can find most of the innovation of Steve jobs's iPhone or Bill gates's surface table but the presentation you will see is more old than those ones...

I do not know about you, but It looks like the user interfaces developed and announced to the whole world by Steve Jobs and Bill Gates are not so innovative (or not their own). Now think about who was the first one...


Apple iPhone presentation:

One example:
Multi-Touch
iPhone features the most revolutionary user interface since the mouse. It’s an entirely new interface based on a large multi-touch display and innovative new software that lets you control everything using only your fingers. So you can glide through albums with Cover Flow, flip through photos and email them with a touch, or zoom in and out on a section of a web page — all by simply using iPhone’s multi-touch display.

Microsoft Surface presentation:

Same example:
Multi-Touch
The Surface display is capable of multi-touch interaction, recognizing dozens and dozens of touches simultaneously, including fingers, hands, gestures and objects placed on the surface.
