When I buy a car, I expect it to run with zero maintainance. If I have to spend every weekend fixing it or pushing it in the mornings, it's time to buy a new car.

You'd need to tweak that analogy a bit to replicate the behaviour here. "When I buy a car, I expect it to run with zero maintenance. If however it does need maintenance, I'll choose to just whinge about it not working all the time, and not bother to do anything about it. Also, all cars from that manufacturer must also be defective in exactly the same fashion. It could not possibly by my fault in the slightest, or I never do anything wrong".
Further teaking required, cos cars have bit's that need routine maintainance, tyres, brake pads, bulbs, windscreen wipers etc... sorry if this is a)obvious and b)been pointed out by another person. :-D :-) :-P
*edit*
Yes, I'm aware certain things need replacing in the world of IT, printer cartridges are the main culprate, always running out of ink, and um... etc :hammer:
