Don't confuse a company's primary product with its purpose. To me, Apple is a personal computing company - putting computing power into as many hands as possible. Today, that's phones - phones and tablets have put the power of computers into far more hands than PCs ever did. And not just when they arrive at work, or get back home - that power is ever-present.
It's likely that computers and what they can do will become even more deeply embedded in our lives. I expect that Apple wants to be a major part of that future, no matter what form the next generation of computing devices takes.
The Apple-that-was existed in a different world. Time marches on. The gripes I read in this thread remind me of the complaints of authors accustomed to pounding out their manuscripts on manual typewriters. There was a time when people interested in computers were interested in the future. Clearly, that's not always the case.
That's right. Apple is and always has been a personal computer company. Where form factor changes have made sense (based, e.g., on technological advances, consumer preferences, societal trends, and productivity needs), Apple has followed - or, quite often, led the way.
That continues to be the case and is why the iPhone is (generally and fairly considered to be) Apple's main product category today. Apple still does robust business with other form factors, to include laptops and desktops. It's just that it does extraordinary business with the form factor that currently makes the most sense when it comes to meeting the majority of the computing and connection needs of most people - i.e., the handheld device, e.g. the iPhone.
Apple's laptop and desktop business only seems less significant (than it used to be) in relative terms; in actuality it's bigger than it's ever been. iPhones haven't displaced laptops and desktops when it comes to what Apple does, they've been added to what Apple does - just as iPods and digital content sales were. Moving forward, other form factors will likely make more and more sense and will thus become a bigger part of what Apple does - what Apple does to meet the personal computing needs of its customers and the world.
