One disadvantage of using physical media is that you use up a very large amount of space when it comes to the size of a console. Apple clearly is looking in that direction as well being that portability in size is very important for them. They ditched the Disk drive for their Mac Book Airs. It may be a sign of things to come for their other doodads.
Nintendo has always tried to have their consoles be small and mobile. Gamecube had a handle for transportation and was very light. And Wii is a tiny baby as well. Also, how will Wii compete if their competitors go digital? They'll be able to charge much less.
