How? It is absolutely inconceivable how much more open it is. Also, the CPU is but a minor part of the puzzle. But still that is still twice as many as apple (good luck exchanging that apple-arm with any other brand). Please let me know how open you think the next apple ARM platform is when you try to boot any OS not written by apple. Please compare that with a computer built from AMD/Intel with a motherboard out of dozens of manufacturers etc. Any ATX power supply etc. Pretty much any PCI-E graphics card etc.

You are confusing the x86 CPU architecture (which is closed) with the PC platform (which is relatively open). > Also, the CPU is but a minor part of the puzzle. But still that is still twice as many as apple (good luck exchanging that apple-arm with any other brand). Even on x86, interchangeable CPUs are the exception, not the rule. Intel and AMD CPUs haven't even used the same socket since the 1990s, and even within those manufacturers, socket incompatibilities are common. Software interchangeability is more of an operating systems issue than an architectural one. With appropriate software shims, though, there is no reason to suspect that (for example) Linux ARM software could be run on an Apple ARM CPU. In fact, it's quite likely that tools like the Android emulator will do exactly that. > Please compare that with a computer built from AMD/Intel with a motherboard out of dozens of manufacturers etc. Any ATX power supply etc. Pretty much any PCI-E graphics card etc. Server-class ARM hardware generally does use similar parts as x86 servers, including power supplies and PCIe peripherals.

  I am not. But also, how many x86 processors are sold outside of the PC platform? They have a symbiotic relationship. The foundation of everything we have today. > Software interchangeability is more of an operating systems issue than an architectural one. Not if the architecture is designed around keeping others out. But just not telling anyone how to do it is enough in 99% of cases. Some hacker might post a buggy proof-of-concept for an obsolete device that no one will run. > Server-class ARM hardware generally does use similar parts as x86 servers, including power supplies and PCIe peripherals. Wanna place a bet on what apple is going to do?
