Apple might have gained all the column inches with its new range of smartphones, but it can't compare to this concept in terms of pure innovation.
'Phonebloks' is a new concept for a mobile phone which you literally build yourself, from a range of pre-made parts, including the battery, processor and ports. The idea is to make a mobile which is never obselete - because as soon as there's a new processor out, you can swap it into the device with no fuss.
Clearly, it's just an idea. But there's an interesting hint here about one potential future for a class of device which arguably has started to stagnate over the last couple of years.
