Hi everyone, I've just purchased a new SP3 online but haven't received it yet. There are some indicators that is been in stock for a very long time (other buyers got devices with absolutely empty batteries, dusty packings and still Windows 8.1 as installed OS). Now I'm a little bit worrying that I will get a very early manufactured device of old hardware revision and impaired battery performance due to the long time in stock. So coming to the point: - Where there hardware revisions during the manufacturing period? - Is the SP3 outdated? When did the production end? What are the latest LOT Numbers? Thanks for your answers!
