The problem isn't that Apple is no longer an innovative company, it's that Apple seems out of touch with what it is that brought people to Apple in the first place, and try to force our focus on their focus, which often doesn't align. A good example would be Apple's push towards everyone using an iPad and do away with a computer altogether, when in reality many people don't want to, so the Mac takes a backseat to the iPad and Apple Watch.
Is Coca Cola similarly "out of touch with what it is that bought people to" them, because they sell bottled water and orange juice as well as their iconic beverage? Different strokes for different folks! All those Coca Cola products are beverages, just like Apple's product line is still focused on computing devices. They may not be the computing devices you prefer, but people buy a whole lot of them. Most Apple customers have come to the company via iPod, iPhone, and iPad, not Mac. A fair number of them have subsequently purchased Macs as well - Mac unit sales today are something like four times what they were on the day iPhone was introduced. Is iOS bad for Mac? I think not!
There's a good chance that the person who reported his pivot from Coke to water is still consuming a Coca Cola product. It's called customer retention - if customer's tastes or needs change, adapt! If there are potential customers out there who do not buy your product, offer them a product they will buy.
Meantime, the sales of traditional PCs keep declining. You seriously think that if Apple focused on Mac that they'd be able to magically reverse that trend? Are you still hoping that, someday, 90% of the world's PCs will be Macs; that eventually, the world will see the light and ditch all those mobile computing devices? The plain fact of the matter is, a PC is more than many computer users need. iPhones and iPads are more "personal" than PCs - a family with one or two PCs is likely to have two or three times as many mobile devices. Companies that deploy PCs to the office staff are deploying iPhones and iPads to everyone who doesn't have a desk.
Does Apple not push Macs any more? Here's a new term for you, "Product placement." The vast majority of computers you see on TV and in the movies are Macs. That's not an accident - it's not Hollywood voluntarily supporting its favorite brand. It's Apple paying to associate its products with the public's idols.
All these "Apple is abandoning its roots" posts smack of team loyalties; as if Macs are the Boston Red Sox and iPads are those damn Yankees. Wrong! You might say iPhone is the infield, Mac is the outfield, iPad is in the bullpen, services are in the dugout, R&D is the farm teams and scouts, and Tim Cook is the GM. You may wish your favorite slugger was still batting clean-up, but if he's been with the club 10 years chances are he's been moved from center field to first base, and is batting around 5th or 6th in the order - not enough speed to scratch out singles at the top of the order, but still capable of contributing to an extended rally.
