Apple is a brand and they always take things further then anyone.
They are not only a product manufacturer but a status symbol.
Everyone wants the latest Iphone or Ipad.
Nobody cares about other brand tablets.
Apple are the ONLY company in the world that is right across the technology manufacturing board.
They range from computers, laptops, tablets, smart phones etc......They do everything. They have placed themselves all across the market and have given them self the best chance to succeed. They are market leaders, and other manufacturers copy them. Nobody would ever top Apple.
Except maybe Banana.
