While I can appreciate what a 5.5 iPhone can do to to apple's bottom line, especially as an apple investor, I have always maintained that people who use phablets look like they're talking to a bathroom tile.
Interesting point, and may I ask, as you are using the physical size of the mobile phone to come to this conclusion, are you also allowing for the variation of the human that is using it?
EG: Would an 8 year old slim girl holding an iPhone to her ear, be exactly the same to you as a 6ft 8" 260lb construction worker?
Would the "it looks right" not scale up in your mind?
Perhaps a 4" iPhone is bigger in comparison to body/head/hand size to an 8 year old girl, than the same 4" device is to the 6ft 8" construction worker.
Why should everyone, From a child with a small body and hands, to the construction worker, have to (in your world) use the exact same sized device.
Can you not see how stupid this concept is?
Why would I need to run calculations in my head in order to validate an opinion I have? This was merely an observation I have and no where in my original post did I say nor did I even insinuate that everyone should use the exact same sized device. People can hold their iPads up to their ears for all I care. They'd look strange for doing it but they have as much a right to do that as I do to form an opinion about it.
I hope apple releases a 5.5" iPhone and I hope you enjoy it immensely.
