This report stemming from Reuters, gives a futuristic impression of what Nokia plans for mobile phones in conjunction with Cambridge University's nanoscience centre.
From a device that can "morph" to fit the function you need, it will fit on your arm as a wrist watch, then can be unwrapped to form a interactive PDA, furthermore is will be self-cleaning (with some sort of nano-membrane that will automatically disperse anything that comes into contact with it). To top it off, they predict it will be able to tell you if fruit is ripe or not through chemical sensors.
Take a look at this clip and see for yourself.
The whole project is believed to be based on scientific research currently in progress, so despite how fanciful it all seems, the future phones will incorporate some, if not all of these features within the next 10 to 15 years.
