Here's how I felt in the moments before I kicked the crap out of an iPod recently:
Perhaps nobody portrayed the insidious betrayal of technology better than Chuck Jones, notably in seemingly endless gags of the ROAD RUNNER/COYOTE series. But in ONE FROGGY EVENING he pinpoints the nexus of frustration in the body of the singing frog--it's not just that it doesn't function, it's that it functions perfectly until it's critically crucial. In fact, it only functions when it isn't necessary, which is something I have detected in hi-tech machinery since even before the days of personal computers.
The now deceased iPod wound up taking the fall for a number of similar malfunctions that have happened of late and I can't exactly say I'm proud of it. Though it was over a year old, I only started using it recently and it only had a few hundred songs on it. But abruptly, for no apparent reason, the audio output ceased, (which kind of defeats the point). The files appeared to be running, but no audio, despite several tests with different headphones. The cost of looking into it at the "Genius Bar" would have only been time and a little $$. The cost of wiping it clean to factory settings (which probably would have worked) would have even been free.
But the cost of kicking the crap out of it? Priceless.
