Microsoft and Qualcomm have officially unveiled the first ARM-powered Windows 10 laptops. Microsoft is calling these devices Always Connected PCs, and they promise to offer up to 20 hours of battery life, instant-on capabilities, and a month of standby. Always Connected PCs will ship with Windows 10 S, which means you won’t be able to run full desktop apps like Photoshop and other Win32 apps that aren’t available through the Microsoft Store. You will, however, be able to upgrade these devices to Windows 10 Pro if you want to. This means you will be able to run full desktop apps, thanks to Microsoft’s x86 emulation tech built specifically for Windows on ARM.
