Re: Cost is the smaller concern
Furthermore, the NHS itself could have its own in-house repository for all the software it needs. This would be copied down, in a controlled manner as appropriate from Debian, Ubuntu etc. That way, if external developers go insane, the NHS could keep going.
1) That would last just as long as the first time the government-appointed contractor (Capita) got their hands on it. Then the repo would disappear into the bowels of the Reading monolith, never to be seen again.
2) What about the interaction between life support machinery and desktop computers? Has anyone actually considered that this is perhaps the main reason why the NHS is still on older versions of Windows? Is someone going to make every ECG or Kidney Dialysis machine Windows 10-compliant?
