As Windows Latest points out, previously this push towards buying a Copilot+ PC was just a general campaign promoting any such machine – whether there's an Arm, AMD or Intel chip inside. Is the reality of using an Arm-based Windows 11 laptop as rosy as this Microsoft blog post suggests, though? For example, want to play Fortnite on an Arm-based PC? So, the answer to whether an Arm-based PC is suitable for your needs really depends on exactly what those needs are. But elsewhere, as Microsoft notes, Arm devices are likely to be a good match for your requirements, while offering excellent battery life to boot.
