Ok, this is quite a long post but please bare with me and read through it
I genuinely cant even begin to understand why so many people are showing there love for the last design.
It looks hideous to me; It just looks like a same old design HTC or Samsung smart phone P.O.S
As for edge for edge screens..... are you serious; how would you hold such a device without accidentally touching the screen?
Getting rid of the home button? if they did that id be getting rid of my iphone; somehow a hardware button where you can; with a quick press + reassuring click, close a program seems infinitely better then a long press on the screen or a swipe to the left, sure this is fine for a ipod nano with no real apps, but think about it your on a website on safari how many times could you accidentally close the page or something.
What id like to see, is a full aluminium body similar to that of the current iPads A tougher, laminated screen to help prevent cracking; and weather sealing! If motorola can make a splash proof phone why cant apple! Think how many callbacks and repairs this would save from people who have got water damage to there iPhones.
The camera on the iPhone 4 needs to be seriously improved in the iPhone 5; while it is a step up from the original iphones i will agree it is appalling; it constantly overexposes and in anything darker then a bright sunny day you get grainy photos with blown out highlights and clipping in the shadows Wether it be software or hardware that needs improving, it needs to be done.
The ear piece needs improving, after 4 years you'd expect them to have improved the earpiece design, so that you don't have to use precision skill to align it with your ear to be able to hear it at full clarity, there are things called surface speakers which would be ideal for this! they work by using the surface they are stuck to to crease the sound, using the front glass of the ihpone they would be able to make the whole surface of the phone able to emit sound, without having to have a small earpiece speaker blasting which would make phone calls more discrete yet infinitely more hearable
This speaker could be used for the loud speaker as well which would allow the phone to give out much louder, clearer audio.
