Declaration of Communication Convenience

1-All devices will be regarded as the same device apart from their size. Three sizes from phone to pad to flatscreen.
What you can do with a phone you can do with a flatscreen and so on...

2-All manufacturers will sign a law that makes them include all hardware in their devices other manufacturers have developed.

3-All operating systems will be the same and by law be the best skeleton made out of all the existing ones that the group of all developers and manufacturers have concluded.
The difference will be in the way users personalize their devices with all the settings like appearance and which apps they run on their devices.
