Imagine a product you will buy instead of your old smartphone: It is coming with a core unit and a default screen with the size of normal phone. And you can buy extra screens or add-ons. You can replace all parts, as soon as central unit is with you, you have 5G connection, all your files and stable bluetooth connection which enables you to use your device.
- It should be so small that you can even attach it to your vr headset
But on the other hand, there is innovation roadmap of cloud computing, even cloud gaming! It is most probaly not going to be mainstream thing, but would be cool to see something really cool.
