When screens go wrong

One often spots display screens, particularly in railway stations, which have suffered from peculiar Microsoft faults and are displaying error windows on top of the information one is trying to read, or which have abandoned informing altogether and are showing just a blue screen of error codes.

I was, therefore, perversely satisfied to spot this giant iPhone model with a "which WiFi network would you like?" popup window, illustrating that even OS X can fall prey to this kind of thing.

Good thin clients must be the right solution here...
