Apple made it crystal clear yesterday that they will be selling Intel-based Macs "for years to come", so what's the question, again?
"For years to come" reads like "for another 2 years". Two is still plural.
The thing is... if Apple still continues to sell both Intel and ARM Macs for longer than 2 years, that means...
1. They can't get ARM chips to perform on par with some of the top Intel chips.
2. That also means platform fragmentation because both Apple and their developers will have to support both x86 and ARM moving forward. That's not trivial effort.
3. It also means... Apple isn't very confident of their switch to ARM either. If they were, they'd go all-in.
And because of those 3 reasons, everyone is expecting Apple to go all-in sooner rather than later. Everyone who is rooting for this ARM transition is hoping that Apple can work magic and make ARM competitive against Intel. I'm of the camp that has seen ARM benchmark numbers over the years and... I am very highly skeptical of Apple being able to come out with high performance ARM chips by the end of this year. But let's just say... either side will have to wait and see.
The burning question then, is: let's say I just bought a $5999 cheese grater, when will software updates stop?
Actually, here's another burning question: why would I buy a $5999 cheese grater now, knowing Apple just literally announced that it's not the future of the company?
