Console games 0% are digital.
PC games 100% are digital. I dont' even have a dvd/cd or whatever drive for my computer even. Have no choice but digital.
3DS about 75% of games are digital. Would be 100% but I get games sometimes as gifts so those are not digital.
Digital is only about convenience for me. As for home consoles, why bother with digital when the system don't move. I want though to be able to bring whatever and as many games on the go with me in terms of handheld, so I prefer digital that way. PC, when I made my pc i didn't spend any money on a dvd drive so been stuck buying digital since.
