AI isn't the star of Microsoft's Copilot PC push -- improved Arm support is

What if you could run an entire Windows PC on a mobile Arm-based chip, bringing the power efficiency and thinner designs from smartphones and tablets to laptops? If you've been paying attention to Microsoft's PC strategy over the past two decades, this song probably sounds familiar. From the original Surface in 2012 (running Windows RT for Arm devices) to the recent Surface Pro 9 5G, Microsoft has chipped away at this dream, only to fail miserably every time. Now with its new Copilot PC initiative, which includes major upgrades in Windows for Arm systems and AI, Microsoft may finally have the answer to its mobile computing dreams. Microsoft's portable PC ambitions didn't start with the Surface line: You can trace it back to Windows CE and Windows Mobile-based Pocket PCs.
