It seems like having thorough, consumer-focused customer support is a huge deal in this iteration of the console war, which is why we were surprised to hear the woes of Ive, a Sony fanboy and owner of a broken PS3. According to Ive's story, he sent in his faulty system to be repaired, only to be told that his warranty had been voided by the massive amounts of dust that had accumulated within the casing.
Here's our favorite part of the story: When asked what part of the warranty says that a dusty system cannot be replaced, his helpful customer service representative told him that dust collection could either be considered customer abuse, or an act of God. We'd like to think that if the Lord did destroy Ive's PS3, he would do so with a plague of locusts, or perhaps a well-placed bolt of lightning. Dust collection just lacks that celestial panache, you know?
Update: The Consumerist has more on this, an apparent confusion within the realms of customer support. Dust obviously doesn't void your warranty, but it seems it was cited as evidence of neglect in this case (and forms of neglect do void the system's warranty).
