At a local eatery, instead of ordering lunch at the counter, I was confronted with an iPad ordering system. What you see in this picture is an iPad behind a credit-card reader, next to a device that prints receipts, next to a bin of numbers to put on the table so they know where to deliver the food.
The iPad is an astonishing device. Nobody really needs an iPad for anything – yet, they keep showing up. Anybody making a touchscreen device has to ask themselves now: why don't we instead just write an app for the iPad?
