That means absolutely NOTHING. For one, the systems are on for 12+ hours a day, 7 days a week.... Do you normally play this much? Second, the PS3s are usually in an enclosed container, meaning tons of heat build up... Do you keep your PS3s in a bubble while playing for 12+ hours at a time? Third, most of the PS3s are test units, not retail ones... They are usually made before the retail ones are... Meaning, more buggy, crappier quality...
