There's a Linux penguin, a fanboi, and a Windows user in a plane, and the pilot says, we're carrying too much weight, one of you has got to go..
The Linux penguin says "I can't go - Ubuntu is just about ready for the mainstream. I have to be around to see the desktop revolution!"
The Apple fanboi says "I can't go - the iPad is a genre-changing leap forward in tactile computing. A bidirectional sense-interface can only be around the corner!"
The Windows user shuffles his feet and says "Those things are all pretty cool. I don't know that I can compete with those right now. But I can't jump either!"
"Why not?" ask the penguin and the fanboi.
"I don't know how, unless you guys show me the way..."
Post script: The pilot, listening in over the intercom listens to each story of hope and aspiration and feels pity for the three. He thinks of his own life - successful, fruitful, and all goals complete. He thinks of his kids, now full grown and out on their own. He thinks of his wife, independent and successful in her own right. He thinks of his career, once brilliant but now in its autumn ebb. He thinks of all these things, and then of the three hopefuls. He is suddenly steeled by resolve. He unbuckles his seatbelt and pulls himself out of his seat. He strides to the nearby external door and, with a great effort, flings it open. The wind and cold batters him as he struggles into the doorway. With one last glance astern, he flings himself into the gale...
...taking the only parachute on the plane.
"Ive worked too damned hard to let my wife and kids live in a world run by those sad freaks!" he thinks as he floats gently down to earth...
