I don'd mind the mugs but what I find annoying is the recent trend for presenters to control what's being displayed on a screen by swiping an iPad. There's no need for it, it just says "hey, look, I have an iPad". Sky News are the worst for it but it has started to creep into other programmes.
I wonder how much is just show, at point someone tapped their iPad to start a video on the screen behind then it switched to a full broadcast quality of the video. Perhaps edited in later.
