To compare directions taken in the computer industry to the situation of 20+ years ago is a stretch. Apple at that time was struggling to compete with the cheap PC market, and Amelio decided to go in a direction that would compete in that market - that ultimately failed, as a market overwhelmingly saturated by Microsoft felt no draw to Apple's offerings at the time. By way of reminder:

In that world, devoid of internet connected mobile gadgetry and phones, and where Apple's prime competitor was Microsoft PCs, it was critical for Apple to differentiate itself as a viable alternative to MS PCs. Microsoft, in the 90s, was more worried about its server offerings in being competitive with Unix - and increasingly Linux - than it was with Apple. That was the main reason for the release of Windows NT around 1994. GUI based OS's like Windows only began to be taken seriously by MS with the release of Windows 95/98, right about the time Apple hit rock bottom. Jobs came back to Apple and made the Mac and its OS a high quality GUI offering in comparison to MS comparatively slip-shod Windows offerings. Serious IT folks, until the mid-90s, still used command line based systems for the most part. PCs, DEC VMS, and Unix offerings at the time were largely command line oriented - DOS for PCs (and a primitive Windows 3.1), X-Windows for workstations manufactured by DEC and SUN. Apple offered the first high quality desktop GUI OS, based on BSD Unix. Combine that solid system with high quality Mac hardware, and voila - the Apple success path was defined.
That was a totally different world from today, where even on this forum, you have people claiming that desktops and laptops are history, to be supplanted with tablets and smartphones. I don't ascribe to that, though I think a large segment of mostly younger people actually do. Most of Apple's profits come from the mobile gadgets, and they are consequently concentrating more on that market. It is becoming harder - again - for Apple to differentiate itself as an alternative to the PC world, with the great improvements not only in PC hardware over the last 5 years, but also in the robustness and diversity of both Windows and Linux as cheaper but viable offerings. That's roughly how I see it, and if Apple loses market in the desktop/laptop area, the main tragedy will be in the loss of MacOS - especially for people who have been using it for decades for their workflow. That is why I suggest licensing the OS to other hardware manufacturers (high end PC hardware is MUCH higher quality than it was 20 or even 10 years ago, and is becoming competitive with Apple hardware). This is why there's been a rise of the Hackintosh crowd, and probably explains why Apple is reinstituting the T2 chip in its latest hardware offerings. Call me a troll, or whatever, that's how I see it. This is a forum for expressing opinion on Apple directions and products, so there is mine.
