Cochlear phones will probably be an early adopter thing in 2015. Though frankly we could do cochlear Bluetooth headsets *now*.

I think by 2015, they'll be implanted in our bodies.

The phone in the video looks like a 2007 model.
Honestly by 2015 I would expect phones to be nearly invisible. I expect them to be built-in to the frames of my video-eyeglasses or tiny like the Motorola H5 but the entire unit not just a headset.
Think about it, 2015 is nine years out. Intel is already planning 45nm chips for 2009. Where will the industry be in 2012 nevermind 2015. Think multicore multi-GHz processors in your phone. MRAM will be mainstream giving us half-terabyte of storage space. Organic polymer batteries will also be mainstream by then. Imagine charging your phone in 30 seconds and having 3 weeks of standby time. All of that in a package the size of the H5. One thing I'm not sure of is bandwidth. If we went to FSO (free space optics) I could see 1-2 GBit/s for a phone. Doing FSO in a mobile package would be a challange. Maintaining lock-on while jogging or driving down the highway might be tough. Maybe multiple radios. FSO, Wi-Max, UWB all depending on what you are doing. We'll see.

It's great as an MP3 player or somesuch, but I thought it was supposed to be a phone???
