Since Apple’s restructuring, which began back in 1997, the company’s product philosophy has been this — make only one product per category, but do it right. Since then, however, Apple’s portfolio has been growing. Slowly, sure, but steadily. So, while back in iPhone 4s days, we only had the choice between a white iPhone and a black iPhone, nowadays, we have plenty of phones, tablets, and computers to pick from. From super-compact, to gargantuan sizes, from less-powerful to bleeding-edge-of-hardware levels.
