Competition breeds excellence. Ask anyone who pays attention to the car industry and they

will tell you that the family-sedan segment is just brutal, with manufacturers fighting tooth and nail over every sale. In fact, that market has become more competitive in recent years. It used to just be the Camry and the Accord fighting for supremacy, but now you have new(Hyundai)and old(Ford)competitors, among others, joining the fight, with interesting, well-made, compelling products. Its a great time to be shopping for a new family sedan. Compare that with the state of the tablet market today. Hewlett-Packard is in retreat. Research in Motion is in a holding pattern. Motorola has been sold and its tablet is now an afterthought. Samsung fights the good fight, hut it trails Apples market share by 50 percentage points. Apple is not just ahead of the pack, it almost is the pack. Now, some would say that this is also a simple result of economic laws at work: Apple makes a superior product, therefore it gets most of the sales. But what would be really great is that, Apple, Google, Microsoft, and H. P. , locked in an epic battle for tablet supremacy, are each releasing new and better products at a furious pace, and each dropping prices substantially at a steady clip. Apple is driving innovation and creativity with each upgrade of the iPad it releases. But this isnt about whether you prefer Apple or Android for your tablet. This isnt about picking sides. As a consumer, I want there to be robust competition across the board. I want Coke and Pepsi, Target and Wal-Mart, Engadget and Gizmodo. If youre a fan of Apple, you want there to be a worthy rival push it, to keep its feet to the fire. If you dont like Apple, you want someone else in the game so that Apple doesnt suck all the air out of the room. And you want Apple to do the same pushing and foot scorching to its competitor that another company would do to it.
