Return of the (Green) Ring

I just received my refurbished XBox360 back from Microsoft. According to them,about 4% of XBox consoles need to be re-serviced. The company that sells the warranties on the console, SquareTrade, says it's more likely around 16%. I think it's higher. Well, it took my XBox (purchased in November 2006) just over one year to succumb to the Red Ring of Death (after a month of fighting it stopped working in the first few days of February). Well, the refurbished unit is up and working. I'm crossing my fingers and hoping that I never need to ship my XBox back for repairs.
