If you were one of the lucky ones to score a 360 at launch you may have had some issues with that console and may have even paid to get it repaired. While that does in fact suck, Microsoft has come to terms with the fact that a batch of the initial run of 360s did have a higher than normal defect rate. As such, any consoles made before Jan 1, 2006 are eligible for free repairs. Those of you that paid for repairs should be eligible for a refund.
I think this is a great move for Microsoft, but it took them a little too long to realize those machines had issues.
