"Our sales would plummet!"

Spotted in a charity shop today for a couple of quid, one Google Chromecast stick, first edition.

It would be nice to have something to show the tablet / phone's screen on the TV, plus the idea of not being tied to Virgin is good, so I buy it.

It sets up ok, albeit with far too many 'let's stop sending anything to the screen' switch offs. I wonder whose wifi network was called [redacted] though?

And in a few minutes, I am broadcasting my phone's screen to my TV...

... when our guest demonstrates that - if you are on the relevant wifi network - you can seize control of what's displayed with no 'is this ok?' to the device that currently has it. It's just given to them.

Presumably this is why people don't use them for public displays, but I think it'd be more appropriate if the box bore a great red label: 'WARNING : LARK'S VOMIT!!! totally insecure to anyone on your network'...
