I wonder if the decline of the PC is faster than the upgrade to Windows 10. I spend most of my time using an iPad and Android phones. I am insiders with two machine running the latest builds, but here I am using an iPad with a Bluetooth keyboard more than the PC. Why? Everything seems to work faster on the iPad. Admittedly, I am not a heavy user. I work with Python, Word and OneNote most days. I wonder how many more have found other methods for doing their work without the PC. So, I am left wondering if Windows 10 will every hit one billion or if it even matters. Will an AI on your wrist be next thing or HoloLens type device take the place of the both the PC and phone?
