The problem being invoked is that the junk food market is much bigger.
There's only one phone maker that is getting to absolutely ridiculous levels of thinness, and that's Apple, while everyone else has understood that people enjoy 3000+ mAh batteries and care more about screen size, overall compactness and weight. I've never heard anyone say they wanted a <7mm thick phone (rather the opposite in fact).
On the other hand, being unable to both charge my phone (which needs it, because the short battery life) and listen to my conference call on headphones is ridiculous.
Only one vendor is pushing for crazy thin phones, and they are sacrificing the needs of their users to do so.
That would be ridiculous. good thing that's not the case in reality, huh? Thanks, twenty year old Bluetooth!
