no more wifi. If you like it, put a cable on it.

Hard to run a cable to my laptop a lot of the time. Impossible to do it from a cell phone, and I do periodically like to print a PDF or other small file I've got on there. But I agree, wifi complicates things. It certainly shouldn't be the default option.

Make printers interchangeable again.

A good decision at a technical level, but we all know why monopoly-pursuing private businesses don't want to go in that direction.
