I love when people like this don't think stuff thru.
Lets start with the painfully obvious.
1) Apple has sold the world on the iPhone being a "RETINA DISPLAY"
This means the PPI (Pixels Per Inch) must be at 300 or above for the device to be considered "RETINA".
That means a 4.6" screen is IMPOSSIBLE. Apple already gets criticized for having two display formats of 1024x768 and 480x320 (with Retina at 960x640). All iOS development is done in either 1024x768 or 480x320. iOS5 continues this programming design. So to make a 4.6" they either have to increase screen size and add a third display format, and there is NO CODE in iOS 5 beta to support this, or they have to decrease the PPI and that isn't going to happen.
So that means at present about 3.8" is the largest display they can make and still retain the "RETINA" trademark.
2) The current thickness is due to the battery. And since there was no leap in battery tech in the last 18 months, we aren't seeing a thinner iPhone in the next year not unless they cut the battery life expectancy.
3) BLUR THE EDGES????? Is he insane????? Apple is all about CLEAN and CLEAR.
4) Removal of the physical button on the iPhone would make it harder for the iPhone to do certain tasks. Like say "ENTERING REPROGRAMMING MODE". I just don't see that happening since the iPhone is just about unbrickable under "normal" use.
So once again, common sense and logic are thrown under the bus so some guy can make a post about a fictional phone that he "believes" will be cool.
