Electric cars.

Mine is still 21inch, I've got a bigger one but its in a room a rarely use, so it just a waste of space really.
I sometimes walk down the street around dusk and cant help but notice how massive some people need their TV to be, even in relatively small rooms they have this gigantic screen where everyone who appears on it is larger than in real life, must be like living with giants.

 

That's a man thing, they can't cope with other men having a bigger one ...

 

The size of TV screens has become ridiculous in my opinion. We have a 32" screen which is plenty big enough in our room. If it dies we will have a real struggle to replace it. Our niece has a 55" screen in a room smaller than ours.
