People need to be realistic. The Mac will NEVER be central to everything Apple does ever again. Those days have past, and they are never coming back.
Just be thankful Apple still maintains a Mac business. Others like Sony have already given up on traditional computers. And Apple will one day do the same and its probably not as far away as some Mac loyalists would like to believe.
Why not emphasize the Mac again? iPhone and iPad sales are starting to tank and up until a year ago when the Mac started being not competitive, its sales were steady or increasing. Makes sense to work on all aspects pf the business rather than something that is declinong (iPhone) or flaming out (iPad).
If Apple would work their magic on a 2 in 1 they could own that field for a while. Running Mac apps along with iOS on a touchecreen would be awesome. Microsoft is 80% there and as much as it pains me to say, it is a good experience. Apple could take that to 11.
