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.
