APPLE THE NAME ITSELF DESCRIBES the QUALITY. ITS PERFECT 4M EVERY ASPECT. IN MY PERSONAL OPINION.I CONSIDER IT AS AN EXTENSION OF HUMAN BODY. IF UR JUMBLED UP BETWEEN TOO MANY OPTION AND BUDGET IS NOT A PROBLEM DEN GO FOR IT.

ITS QUITE MORE BETTER BY PUTTING A HEADSET. 4.TOUCH SENSITIVITY IS UNCOMPARABLE. 5. CAMERA IS VERY GOOD WITH TRUELIGHT FLASH.I M A HOBBYIST PHOTOGRAPHER VERY MUCH SATISFIED WITH IT. 6.NEW TECH LIKE FINGER ID DETECTION IS WORKING VERY NYCLY. 7.BATTERY BACK UP IS VERY GOOD. 8.SPECIFICALLY SPACE GREY COLOUR IS ATTRACTIVE. D APPLE LOGO IS QUITE MORE VISIBLE IN WHITE. 9. CELLULAR , 3G AND WIFI NET
