PowerPC has a weakly ordered memory model, so older Mac programmers are no strangers to this sort of stuff.
There have been many multi-core ARM devices out in both the Android and iOS world for a few years, and I haven't heard too many complaints. I think most good high-level programmers know that they need to use high-level locks provided by the SDK, while anyone writing code that actually needs to deal with memory ordering probably already knows to use barriers some of the pitfalls of different ISAs.
