Bravo for repeating the obvious and another round of applause for missing the point entirely.
Based on his opinion, he feels that it may be the next logical step for Apple to separate the buttons. Do you see the problem with this?
Stating my opinion is just as meaningless as him stating his own, because in the end, we both don't have a clue as to what Apple will do.
It is however, rather pointless to debate on a future modification and insist that it improves upon the user experience, when it is in fact, only based soley on opinion alone with no valid cause for change.
And you think I didn't understand that? I thought it was funny that instead of just telling him what you just told me, you expelled the energy to explain your point of view to him, after you stated that basing these assumptions on opinion is meaningless.
