I used many average budget android mobile whiever came in market new, after a year it cant be so easy to use that mobile like first when we bought, I need to buy every 1 year a new mobile. after I bought an apple iphone 5c I dont need to replace my mobile with any in my budget mobile.
So thank to you apple founder steve jobs and thanks for doing making slim design , and I hope so in future there will be technologies like in avengers and ironman found by apple company, so I m just waiting for that day.
