Linux stills runs on more computers than any other OS in the world.
Windows runs on between 1.5 and 2 billion PCs/hybrids/tablets/smartphones.
How many does Linux run on? (And don’t quote Android activations per year; activations does not equal the number of installations that are actively in use.
Oh, btw, Windows also runs on millions of ATM machines and on millions of checkout register devices in large and medium and small shops. I don’t see any Linux screens at checkout counters. Windows embedded is also used in many devices not directly known to people, such as consumer electronics, set-top boxes, gaming systems, automobiles, and many other uses. It’s also going to be powering a few billion IoT devices. IoT, remember that? MS is now a leader in IoT tech and software.
But, who’s counting?
