@ Mike Bird
What you say is pretty much what I said, but longer. I simply paraphrased it.
For what it's worth, all electronic goods imho should be guaranteed for 25 years. You know why? Because that's the industry standard lifetime for all semiconductors that have passed qualification. To pass as a qualified part they have to pass stress testing the equivalent of 25 years use. So people who seem to think a PS3 should last 2 or 3 years before it goes bust have a very low expectation. For any failure outside of pouring water inside it, wrapping the entire PS3 in plastic so it's airtight or dropping it from a height, then there must be an inherent fault with the goods. It could be a weakness in the silicon, or a poorly bonded wire, but that fault is inherent. In fact about the only thing that could fail and be even reasonably expected to fail is the fan bearings.
And before anyone says it, I was an electronics engineer, my job was testing semiconductor components before then moving to optical components. The most common cause of failure is bad design, not bad products. Don't buy a Ford from 1998-2000 ;)
