There are other Google Apps that don't work as great on a mobile device. Try Docs on an iPhone, for example. Also, imagine you need to print out a 30 MB PDF that somebody just emailed to you.
Not enamored with QR codes as a solution, though; I still maintain that the vast majority of Americans have no idea what they are and find them, in general, to be a gimmicky pain in the rear. I agree that what you described would actually be more useful, but also probably harder to do (offline = native app).
