And Motorola had true wireless earbuds earlier, etc.

Apple is about polish, not novelty, but a ton of people are obsessed with the idea of Apple as being "groundbreakers" everywhere.

That’s one thing macOS does well: legacy support— at least for x64.

for now…

Any program written for the .net clr ought to just run out of the box.

Both of them?

There’s also an x64 to ARM translation layer that works much like Apple’s Rosetta.

Except for the performance bit.

ARM processors use a weak memory model, whereas x86 use a strong memory model. Meaning that x86 guarantees actual order of writes to memory is the same as the order in which those writes executes, while ARM is allowed to re-order them.

Usually it doesn’t matter in which data is written to RAM, and allowing for re-ordering of writes can boost performance. When it does matter, a developer can insert a so-called memory barrier, this ensures all writes before the barrier are finished before the code continues.

However, since this is not necessary on x86 as all writes are ordered x86 code does not include these memory barrier instructions at the spots where write order actually matters. So when translating x86 code to ARM code, you have to assume write order always matters because you can’t tell the difference. This means inserting memory barriers after every write in the translated code. This absolutely kills performance.

Apple includes a special mode in their ARM chips, only used by Rosetta, that enables an x86-like strong memory model. This means Rosetta can translate x86 to ARM without inserting those performance-killing memory barriers. Unless Qualcomm added a similar mode (and AFAIK they did not) and Microsoft added support for it in their emulator, performance of translated x86 code is going to be nothing like that of Rosetta.

I recently bought an M1 Max and I definitely regret migrating data from my Intel MacBook. I’ve had to reinstall nearly all the apps anyway. Less compatible than I was expecting. Overall happy with it.

My phone is now 7 years old and it still works perfectly. Maybe not the newest of the newest games, but i don't care for games on my phone anyways. And the amazing contributors keeping lineageos up to date for my phone model makes me not need a newer phone :)

If power consumption is lower, that means can have a more compact cooling. There's a lot of people who would pay the premium for longer lasting and lighter laptops, myself included.

ARM is RISC (or at least a version of it).

Samsung make exynos chips which are arm. But Samsung even uses qualcomm in their phones in other regions so it's not unusual
