Just like Del-boy’s

Still works though.
Just imagine how much it cost for Apple to make something that you could use to write on an iPad. Then they called it an Apple Pencil as if they’d invented it.
I’ve had pencils for years, even had one with an everlasting lead and several with built in erase functions on the end. Different colours, different line widths an even ones that you couldn’t rub out.
Progress - hah!
