I was mostly referring to the laptop/desktop space. For smartphones apple is ahead but not by much, for the tablet space apple is about the only player indeed.
Indirect competition to anything Apple might equip with Mx type of SoCs will mostly come from QCOM and hopefully Samsung eventually. QCOM has slated to announce its first laptop SoC next year if memory serves well. Other than that Intel/AMD might do an outstanding job, but the higher bets for future laptops might be rather directed in longer battery lifetimes/increased power efficiency.
