because you don't need to sell devices to customers who use them. you need to sell devices to so called journalists. they have no idea what they're writing about, but to make up for this, they agreed on judging products by certain buzzwords they find on the box. these buzzwords change over time, but for now, we have to live with the fact that one of these buzzwords is "touchscreen". (another one is "intuitive". nobody knows what it actually means in regard to an electronic device, but it has to be printed on the box.)
