Is it me or have we reached the end of the road of mobile phone innovation? Is this going to be Apple's downfall as something like 70% of their sales are from iphone? We've had many years now of mobile phone enhancements and features but it seems like there isn't a lot more we can do on a phone. The next breakthrough ipod/iphone isn't going to be a phone at all. How many more times can we put a better chip or a better screen or a new camera into a phone at this point and have consumers seriously give a crap? Feels like things are going stale.
