Seeing through the Windows

Windows 8 is interesting. It moves away from the traditional Windows Start menu and into the world of clickable icons.
For decades Microsoft have made millions because the world has been compatible with Windows.
Most companies use Windows, so most commercial software is created to run on Windows.
Windows is on most of the computers we buy to use at home, so most of the software written for people at home has been created to run on Windows.
And most of the printers, scanners, cameras and other devices we buy come with software created to run on Windows.
The world works on Windows.
Or it did until Steve Jobs showed non-geeks how to download music and Google’s Android made millions of phones cool.
Now people are as happy to touch apps as they are to start a program from a menu. The Windows spell has been broken.
I bet there are more programmers writing software for iPads and Androids than there are writing code to work on Windows PCs.
Windows 8 shows Microsoft have accepted this. Why is it taking so long for the people who make printers and other peripheral bits of kit to provide an app as well as a Windows CD for people to set them up and use them?
