I’m not sure the metaphor works, I’m the only person who uses my computer, I don’t go down to the computer station and wait for someone to drive the public computer along.
A pc is much more like a car than a train; it is something you own and you are responsible for. You get to choose the operating system and the software that is installed, you get to choose the colour of the box.
Linux isn’t public transport, it’s a factory that lets anyone come and help build a car. If you have a better idea for a steering wheel, or think that there’s a problem with the engine you can fix, Linux lets you into the factory to make those changes.
This has been my favourite tech story for the past few years, I hope the train company gets put in its place properly this time.
