The last time I bought a Microwave (about four years ago) I remember specifically looking for two knobs just like this. I remember the first microwave I used in the nineties and it worked similarly - just like an oven (also two knobs normally) everyone knew how to operate it almost instantly. The one I eventually found was also the cheapest one and almost the only one. The more expensive models were usually designed around a button interface and had plenty of features like thawing, grill, and so on. Of course all these extra features amount to little more than switching the magnetron on and off according to a programme. Go figure... My mom (who has since taken over it) was very confused about the one second delay between adjusting the time and the microwave starting (just like the linked one there was no start button). She had obviously been accustomed to pressing buttons to get it to operate how she wanted. Which just maybe goes to prove that what is "simple design" is not necessarily the simplest interface but the interface most aligned to the users' previous expectations on how this particular item should work.
