Review on Raspberry Personal Computer Keyboard Accessories by Brian Davis

- "Beginner's Guide", chapters 4 and 5 are poorly written. There isn't much useful here for those who have already programmed, and for a beginner it will be very confusing as the chapters "see if you can copy the instructions exactly" without conveying the concepts. There are also mistakes (or assumptions) in the directions that are very difficult for a beginner to overcome. Hopefully there will be information worth reading in Chapter 6 and beyond. A small point about the Pi 400: it needs a power switch. Removing and reinstalling the power plug is not ideal.
