Today we have Apple with diversified Mac, iPhone, iPad, Watch and Services businesses. And soon to add Glasses and Car if predictions come true.
Apple was less big in the 80s than today, but they were still huge. There's a reason they lasted a decade despite uninspired management.
The situation is remarkably similar, if you ask me. Just replace IBM/MS with Android vendors/Google.
† Edit: on second thought, it's not necessarily a plus to say Apple is working on many different products. That was part of the problem post-Steve. See: https://youtu.be/xchYT9wz5hk
That is why what they ought to know better now. Mind you, they probably do! I think they just worry about the next few quarters. As for the long-term, little personal incentive because "let the next guy or gal deal with that after I've moved on"
It's why I switched to a PC in the 1990s. And everyone I knew. And everyone I met, read or heard about.
What was the point buying a Mac, when you could buy a faster, more compatible PC running Windows 95, which was pretty Mac-like, for half the price?
I'm not sure what you mean about performance? When I switched, I had the impression PCs were outperforming Macs by a long shot. That must have been within a couple years of the Win95 release. I should probably hedge a bit there because my memory might be off. It was a long time ago.
Performance: Macs were quite competitive, or even better than PCs for quite a while. It was only later as the Intel juggernaut kept going that Apple started to get steamrolled and had to switch off 68k. They regained the crown for a little while, but even the G3/4/5 were quickly overtaken by Intel.
The timing didn't work out for Sculley in '93, but maybe Tim will have better luck. Maybe "this time is different."
