A cunning plan?
Raspberry Pi turns out to be a bit of a success.
Thousands of kids are getting to use Linux and possibly liking it.
Original Pi is too weedy to run Windows.
Problem.
Let's have a chat with the Pi Foundation and become buddies...
New Pi released with 6x the CPU and 4x the RAM. (For the same price?!)
Get a sawn-off version of windows running on it ("runs apps written in HTML", wtf?)
"Developers will need PowerShell running on a connected PC". There's the payback / lock-in.
Have chat with our buddies that run the National Curriculum and get some Windows-based Pi modules made mandatory.
All Pi's in schools must run Windows. Putting Linux on them is forbidden as a security risk / hackers training tool.
Profit.
Damn, that takes more than three steps. Ah well....
