What is the next unique feature can a mobile phone have?

I do believe that the next generation of mobile phones will allow us to do video conferencing. Right now, it is still considered as luxury but in a few years from now, the rates will be cheaper and everybody will be able to do video conferencing. Maybe the next generation of mobile phones will be focusing more on health such as blood sugar monitor, blood pressure monitor and body temp monitor. I'm just guessing though.

Interesting question. Some PDA with infra-red can be programmed to be a remote control. So a cell phone can do that too. Cell phone becomes more like a small laptop computer. An electronic wallet may be. Heard that in Finland they have done that already. I would like to use my cellphone to beam money to my friends when we go out. Also, a small phone-attached projector so more friends can share a movies clip.

I really can't imagine.. but perhaps something that is not so important but will make everyone want to buy one.. Isn't it with the ones we have now? Couldn't we pass without all those features that make us and our kids desire to change? I really think that the power of publicity is enormous.. and make us desire things that are not so important only to sell more and more..
