Most citizens of Startupland have probably been there: You're about to give a presentation of a slide deck and suddenly Powerpoint won't open, or you're in the middle of a demo when your app fails.

Apparently even tech tycoons aren't immune to glitches. Take this presentation from Microsoft, for example, where an exec goes to demo the new Surface tablet in front of an audience and it freezes.

As soon as he says, "We can see here, I'm running Internet Explorer. I can browse smoothly," the tablet freezes, and he's forced to finish his presentation with a bricked Surface in his hand.

At least there was no blue screen of death?
