I really do not think changing the look of ANYTHING you own a big deal! We paint our homes,choose window coverings,give our cars added effects---- So really, why bag on a person for changing the desktop of his/her pc? Do you feel that bagging on peoples choice of changing the desktop Is any worse then spending your time nagging them about It?
Is this truly a big deal to you? If you enjoy arguing about what people do, You should spend that energy addressing this worlds REAL problems. Like taxes,unemployment,children starving,mothers living In a car with 3 kids--- Talking about someone wasting time doing something pointless----LOOK IN THE MIRROR. -peace-
