1000%. Used PCs are the way to go over a raspberry pi unless you have specific accessories or something. Almost everyone just uses a raspberry pi as a USB host or for network services anyway. Gpio use cases tend to be better served by Arduino or esp32 too
I hate how people mix up correlation and causation with JC Penney and it’s couponless trial. The company was ALREADY very much on a fast track to bankruptcy when it decided to try removing coupons - that’s why they tried it. It didn’t make enough of a difference to pull them out of the nosedive they were in.
It’s not that not doing coupons doesn’t work, it just didn’t save a failing business.
