Since this issue is attracting a lot of attention on the forum I am interested to see if there is any correlation of data across build weeks (especially starting now if this gains more traction). If you post your data here I will compile it into a spreadsheet and make it available somehow. Use this link to check for the details, then we can keep it consistent. Enter your serial in the top left search box: http://www.appleserialnumberinfo.com/Desktop/index.php Post your: Order Date Arrival Date Build Week (via link above) Production Number (via link above) Screen Manufacturer Configuration (CPU/RAM/Flash Size) Image Retention (Acceptable, Unacceptable, None) For Example: Order Date: 13/09/2012 Arrival Date: 17/09/2012 Build Week: 38 Production Number: 830 Screen Manufacturer: Samsung Configuration: 2.6/16/256 Image Retention: None I know the Image Retention section is subjective but it's interesting data to collect on people's opinions of it. I will calculate age from the difference between Arrival Date and the date you post the data. By submitting your data here you are giving me permission to hold it in a persisted form against your MacRumors username, only post if you agree to those terms! If we try to keep other speculation in separate threads we can keep this relatively tidy. Thanks.
