Likely a common sentiment lately.
Wall Street should take notice. Apple seemingly only will once their stock takes a prolonged steep dive. Killing off Macintosh piecemeal will be equivocal, if even now Wall Street's attention, as that was Apple's core business once. Everything iOS is dependent upon iPads which have plateaued and the possible merits of the upcoming iPhone 8. Apple better hope it sells like hotcakes. Because right now they seem fumbling for a viable way forward.
Apparently they were broadcasting "courage" as less warning than to shore up their own resolve to eviscerate the Macintosh.
Problem is the Macintosh line remains a very profitable enterprise with loyal customers which could easily stand separately on its own, if managed properly. Mr. Cook & Co. are all in on iOS, but that is a legacy from Steve Jobs as well. It could fall as swiftly as it rose, especially if mismanaged.
Foresight and innovation is precisely what Apple needs at this juncture, and exactly what seems lacking. The market will be ruthless. Moreover his iOS customers will prove far more fickle in their loyalties; the moment an Apple logo becomes uncool in a coffee shop, game over.
Tim Cook had better hope his vision for all iOS is sound. As a large contingent of once loyal Apple customers will not weep should he fail, that they needed, used and loved since excised.
