Personal computers running Windows were at the center of our technology world for twenty years. I’ll tell you about the Surface Laptops next week. They’re gorgeous, thin and sleek and sexy. Microsoft will soon release Surface Laptops, beautiful devices with the high quality appeal of the Surface tablets in a traditional laptop form factor.Microsoft hopes that everyone will embrace this as the future of Windows – first developers, to populate the Windows app store with the programs we want, and then businesses / schools / consumers, who will be attracted by simplicity, security, and reliability. The most important limitation: Windows S can only run programs delivered through Microsoft’s app store. It is based on Windows 10 Pro but limited in important ways to improve security and performance and extend battery life. Microsoft will soon release Windows 10 S, a new version of Windows 10.One common element is that Microsoft will fail at both of the new ventures it announced. Microsoft made two big announcements this week at an education-themed press event.
