Media=All vs Media=Screen

Question

It seems like recently I have seen many more people starting to use media=\"all\" vs media=\"screen\" in their stylesheets.

My question is

Answer 1

media="all"    // Used for all media type devices ( its default under html 5)
media="screen" // Used for computer screens(default value  for html 4.01)
