This made me chuckle. I have a Macbook, but I take my mouse and mouse pad everywhere when travelling. I admit that the shortcuts are amazing and that's all my husband ever uses. However, he cannot use a PC because he's only ever used a Mac. Whereas, I've always used a PC and only started using my Mac for about 4 years now. I might occasionally use the Mac shortcut cut + paste, but that's about it.
You have reminded me to set a goal and practice working without my external devices 😁
