I found my serial number in "About This Mac", now how can i tell when it was built? And does the first week of 2008 include the week where the year transitions? i.e. Dec 30 and 31 are in the same week as Jan 1, 2, 3, 4, and 5, so will this count as the first week of 2008? Or is it the week after where ALL the days are in 2008? hehe.
