Thank god the NHS has a 9 year contract with MS:

They were going to originally use open source (ie. free) software but at the last minute changed their mind.
No doubt they were taken to some nice lunches by MS who also slashed their normal prices to retain domination.
I wonder what disaster looms in the future for them.
