Cat is out of the bag and it has skipped one generation (Windows 9) altogether to be known as Windows 10. The above picture says it all. From Phones, to Internet of things to Tablets to Desktops to TVs, all will run “One Windows”. In words of Microsoft,
Windows 10 will run across an incredibly broad set of devices – from the Internet of Things, to servers in enterprise datacenters worldwide. Some of these devices have 4 inch screens – some have 80 inch screens – and some don’t have screens at all. Some of these devices you hold in your hand, others are ten feet away. Some of these devices you primarily use touch/pen, others mouse/keyboard, others controller/gesture – and some devices can switch between input types.
Windows experience will be tailored for each devices though and there will be one application platform for our developers
We’re not talking about one UI to rule them all – we’re talking about one product family, with a tailored experience for each device.
And across this breadth of devices, we are delivering one application platform for our developers. Whether you’re building a game or a line of business application, there will be one way to write a universal app that targets the entire family. There will be one store, one way for applications to be discovered, purchased and updated across all of these devices.
This can be a huge step forward for whole Windows ecosystem.
