Not the story, Windows 8 still struggling "Other" kicking off big time
Despite the monster success of iOS there really has not been a shift to OSX. OK a steady very slow leak but is hardly worth the ink to print the headline.
Despite that consumers are forced to use it and on some pretty crap adware in my experience. However W8 is hardly growing! people don't like it, W7 was a great successes and people do( quickly abandoned by MS ) even in this environment Linux is going nowhere Apple is I bit better than flat. "Other" is the one worthy of the story. I presume this is Chrome and down to the inexpensive hardware. People just give it a go. given the rise and rise of the IOS pastiche Android, it seems that this is the real threat to MS not OSX
