My idea is to set up a webcam on a computer screen at first, and perhaps then become more technical.
This could lead to the iphone simply serving as a portal between the screen and your home computer.
Then all you would need is a monitor and you have a fully functional computer wherever you go.
The ideas are limitless:
- full computer access wherever you go
- access to an xbox 360 wherever you go
These ideas would require fast internet connections, but they are feasible.
