> ARM was in phones and PDAs long before Apple used one in an iPhone and it got there because of performance/watt. It had already reached 100s of millions of users before the iPhone was released.

I put the iPhone and Apple as an example since they were very unique in customizing ARM for mobile devices. Sadly, we are waiting for M1, M2, M3, and M4 processors in the PC space.

Regarding a timeframe, it was around XXI century that ARM reached its users. There was a big time gap between the 70/80s microcomputers and mobile devices. Palm Pilot, for example, use the Motorola 68k. Psion started using ARM devices in the late 90s, before that they used an x86 variant. Newton was a failure, although it shows Apple mind clarity about ARM.
