Hey Dave and Chris,
Just wanted to answer your question/thought about mains fusing in plug packs…
I do not think fusing within the transformers is typical for modern switch-mode power converters. It is (and was) more prevalent in larger 50/60Hz step down transformer bricks. (There’s physically no space in the high frequency switching transformers! Look at the dimensions for an RM5 or RM7 transformer.)
In switch-mode plug packs, the popular choice is a “sub-miniature” type fuse. You can look up Littelfuse 400 series for an example.
You kind of butchered the Cortex family explanation. Basically Cortex-A is ‘application processor’ used primarily for tablets, phones, computers and the key feature is that they have memory controllers for interfacing GBs of DDR3 memory. The Cortex-M are ‘microcontrollers’ which typically have tightly coupled internal RAM. A cortex-A will typically run an OS kernal. A cortex-M will run on bare metal. Then comes cortex-R that are somewhat specialized for RTOS.
