iphone is my favorite phone till date, it is designed by apple inc.
I have used iphones for the last 15 or so years. I can't see changing any time soon.
That's a good choice! You know, Steve jobs instructed his employees to investigate touch screen devices and later they invented iphone
That man had an amazing mind. He knew technology and marketing. 
Yes indeed! Jobs and Wozniak together created apple and are considered as pioneers of the computer revolution.
They single-handedly changed the way the world works.
Yes they did! Have you seen 2015 film 'Steve Jobs'?
Not yet, no time for movies right now.
I would suggest you must see it. Michael Fassbender portrayed Steve Jobs and he did a great job!
