You buy your dad a chair for Christmas, fine, but what about next year? Like, he already HAS a chair! NOW WHAT? Not a problem with gadget gifts. Because by the time next December rolls around, it'll be out of date. So Dad's getting the newer version of the thing he got last year!
When I was young, if you asked for a gadget for Christmas, you'd get an egg beater and a bowl, and they'd make you make guacamole for everyone the whole day!
