Seconding the number of people who didn't have computers at home, and hence had problems gearing up to work from home...
I was stunned to hear of the number of IT personnel who didn't have computers at home that could be used to connect to work.
Many had a laptop computer (or more than one) in the house, but they were used for the children's schooling, and schooling from home.
I was the other side of that fence, I have a Windows 10 laptop, and a linux desktop system.
(Both of which I was able to setup for work-from-home)
The powers that be were stunned to find that linux worked, but as far as I know, there were only two of us doing that.
