I strongly believe, this would be just the beginning. Mobile phones give you three things - (recently, Horsepower), Mobility and Identity. And there are a plethora of things that could be powered with a combination of the three.
Yes, this is what we hope the future looks like. But, for this to happen, the device manufacturers need to collaborate. We still don't have a universal phone charging adapter. Imagine how messy things will get if Apple, Samsung, Nokia etc each start making their own docks which are not compatible with others.
