How something looks comes into play in almost everything we humans do. People go to the car dealership and want to buy a particular vehicle because it looks good to them but they know little to nothing about it's fuel economy, reliability, or safeness. They'll buy a dog based on literally nothing but how it looks. A lot of audio components are quite literally audio jewelry (Dagostino stuff being one of the best examples) with prices to match but not sound quality.
Personally, I've been a function over form person for as long as I can remember but I think I'm definitely in the minority.
