Apple had a few near death experiences and might not have survived.

One of those early near death experiences might have been Jobs fault (going at the Apple /// and the Mac when, in retrospect, the Apple ][ could have been evolved more aggressively) but he helped bring it back from the brink later on.

Android deserves a lot of credit for the success of iOS in that a zombie mobile OS that doesn't have to be profitable has displaced a competitive mobile OS. A similar kind of fragmentation has bedeviled the Windows (and Linux) PC as well as (from the viewpoint of Windows) distractions such as Azure (good business) and XBOX (bad business.)

Intel deserves a lot of credit for the success of Apple too because for 15 years Intel has had no strategy to translate architectural improvements to experienced performance for client PCs. The way they've gone about SIMD is an absolute disaster, like by the time we can use AVX-512 in mainstream software everybody will have moved on to ARM. Charlie Demerjian would talk your ear off about how the tech press has been uncritical about their hyperscaler/HPC patter, never reminding you that client PCs are still the bread and butter of their business -- pander to the likes of Amazon and they will use any cost savings they get to invest in ARM. It's suicide.
