They were using AirPlay. Or trying to. Three MacBook Airs (because they look cool, apparently), presentation made on one of them. Couldn't make it play. Emailed to another. Ditto. And to another. Ditto. (Act of ignorant desperation: What can we do with it? I don't know. Why not try emailing it. That might mend it).
It was funny (yes, actually funny) watching the floundering attempts of their coolnesses as they gradually realised that Apple stuff, like all other computer stuff, isn't full of pixie dust and doesn't always 'just work'.
Of course technology fails sometimes. That's normal. What's abnormal is the marketing mythology that's conned so many into believing that one particular company is run by unicorns and fairies and makes magic, rather than bog-standard, overpriced hardware assemblages wrapped in pieces of shininess. And, irony of irony, a lot of it works less well and is less able to interface with the rest of the world than most other computers. And a lot of the software struggles more than the alternatives.
Of course people choose different products for different reasons. Form over function has never been a reason I could understand, except for those with a desperate need to cuddle their tender egos.
Of course, YMMD.
Hey, who remembers the coolness of 'shell suits'?
