I never heard that Apple invented switching power supplies... how common is that train of thought? I've been using them since way before this article was written

The article is neither making or debunking that claim. It is debunking the claim that apple revolutionized computer power supplies by borrowing the switching power supply design used in oscilloscopes. It’s the second sentence of the post.

For its personal computer contemporaries, the TRS-80, the Commmodore PET, the Apple II's use of a switching power supply was unique. I had never heard that they invented the switching power supply.

Apple's price premium meant they often could introduce the next cutting edge technology that would soon become ubiquitous when the prices came down.
