I used to have that sentiment but ever since I have seen Apple's financial reports, it became easier to see why. The percentage of revenue from Mac line up has been sub-10% for a while, and lately is even less than web services. As a publicly traded corp they owe nothing to anyone but shareholders, so let's put that out of the way.
As for all eggs in a basket, I do agree but bear in mind we are seeing the landscape outside of their scope, so whatever amazing stuff they may actually have in their "pipeline" is of course unseen, but it can actually exist. Pulling out of display and router businesses are clear sign of fat cutting. I don't think Macs will suffer the same fate at least not soon. If the other tech competitors are anything to be referenced at, it is obvious that Apple has been trying to work on numerous fronts for quite some time now, namely in autonomous vehicles, AR, and perhaps some form of smart home network, may or may not involve a TV set. They are likely trying to push a cohesive package of digital lifestyle that have devices and services intertwined with each other, instead of the "one Mac being the singular digital hub" approach that we are used to.
But anyway all these are of course simply speculation, I am as frustrated as everyone else here being one of the long standing, Mac-using creative pros myself. For a company who used to do great things so consistently in the last decade, I still hold some hope that those hats may in fact have something up their sleeves, even without Jobs.
