Microsoft, Apple and Google are three of the world's most influential tech companies. Billions of people use personal computing platforms, tools, or devices they supply or inspire.
From cloud, AI, smartphones, PCs, apps and more they've created a multi-ecosystem personal computing world that supports an increasingly-interconnected, and overlapping range of computing scenarios.
Personal computing is no longer restricted to desks as a sedentary experience. Nor are users completely liberated from that setting and capable of existing fully in the mobile space. They regularly transition from desktop to mobile and across ecosystems and devices because no single platform and device moves seamlessly with them across contexts. Microsoft, through Windows 10 and Surface, has embraced a platform and hardware philosophy that drives devices that conform to users' contexts. Despite the smartphones success as mobile computing's focus, Microsoft's rivals may be missing an important industry shift.
Their platforms are not mutually exclusive, though - I use Google, Apple, and Microsoft platforms every single day. Take what suits you best from each of the platforms.
