Re: Older stuff WAS simplier...
That's the control you don't need. Do what every microwave does, and I assume did, and just have a door. You pull it open. However, while I'll be the first to agree that I need very few microwave buttons, I'll take a number entry pad over logarithmic dial every time. I'll find how long I'm going to heat the things I typically do. Entering it at that point does not require me to look at the labels. Sure, there's an element of muscle memory in the dial which may make it more straightforward, but I find pressing 1, 5, start is pretty easy.
