Since Windows has been around for decades and has excellent backward compatibility, there are tens of millions of PC apps. The vast majority of those have not been recompiled to run natively on Arm PCs. While that number may seem staggering, many people use a relatively short list of core apps. Heck, I know people that literally only use their web browser and Office.
According to Microsoft, over 93% of total minutes spent in apps are in apps compatible with Arm devices. 87% of total app minutes are spent in apps with native Arm versions (though so may not be using the native version). Microsoft highlighted that emulated apps on devices running on a Snapdragon X Elite are over 2x faster than Windows on Arm devices from the previous generation.
Those figures are noteworthy and suggest that many can use Arm-based PCs for everyday computing, but they still indicate a gap in the platform. If one out of every 10 apps you use is not native to Arm, you may not even look at a PC with an Arm chip inside. I agree with Microsoft that emulated apps are better than ever, but they're still not native. And as mentioned above, there are some apps that don't work on Windows on Arm at all.
Copilot+ PC findings
Microsoft tested performance, battery life, and application capabilities of Copilot+ PCs throughout the year. One round of testing wrapped up in May 2024 and then another round concluded in September 2024 following the release of Intel and AMD-powered Copilot+ PCs. That later round of testing also allowed Microsoft to stack Copilot+ PCs against MacBooks running macOS Sequoia. Notably, the comparisons stack Copilot+ PCs against M3 MacBooks since M4 MacBooks did not ship until November 2024.
