I want a GPS, compass, infrared vision, gyroscopic (rotational sensors), accelerometers, optical zoom, be able to sense the frequency my cellphone is broadcasting on. I want to feel electrical and magnetic fields, be able to distinguish between every smell, have 360 degree radar/lidar, and optional echo location, temperature sensors, I want to be able to think http requests and sense the responses.

I want to be able to close my eyes, disconnect all of my 5-10 senses and plug them into a computer generated world where the rules are as I define them. So I could be lying in bed yet genuinely feel that I am running a marathon.
