We also have these big coffee machines at work and they're very cool because when you're walking to a different one it's kind of random which mix of products you'll get offered just because there are so many drinks and each one is programmed differently. And I agree that it makes sense for these types of machines. But my personal one has literally two options to choose from. However, the touch screen is old technology in contrast to the machine itself, so the handling is rather awkward. Also, it had to be replaced already because it suddenly stopped working for no actual reason. I think that the logic behind not just putting two physical buttons on it is that some designer thought it looks cooler with this big screen full of colors - and he may be right, but UX should really be more than just looks.
