Apple should have had all their phone with varied versions of OS according to hardware compatibility. I purchased my first iPhone in year 2013, it was iPhone 4s, what a piece of art, it was great but now it is useless (yes useless) because it is not compatible with the new OS. Right now I have iPhone 6s, and I must say it is as good as dead now, but I made my mind to switch to android now. Now the question is how many times we going to buy iPhone?, on an average a serious iPhone lover had spend around at-least $5000+ so far. WTF??? No wonder why Apple became world first trillion dollar company. Good for them, bad for people's pocket.
Of course. All the systems made especially to make us buy new phone. In the case of apple is vry clear. But androind is better of couse. Sometimes even with android, if the phone is not expenssive it maybe slow. But it's better than the tricky ios of course.
