Hi guys, need some advice. I've had an iPhone since 2008, and it is my first Apple product. Since then, I've owned the same first generation iPhone and am thinking of purchasing something. I'm a 17 year old student, studying for A Levels - currently in first year of A Levels. For the purpose of my background, I am studying mathematics and the three sciences. Should I purchase a new iPhone this summer, or should I go with the iPad? - or neither?
