We already knew that companies ship hardware in the most ridiculous and oversized boxes, but come on Microsoft, shrink-wrapped retail boxes to sell a numeric key? I understand your desire to sell, but this is a total waste.
In case you are not aware of it, Windows 7 Anytime Upgrade allows you to go from one version of Windows 7 to the more powerful one by just entering a key. They key is just a serial code that activates features in your existing copy of Windows.
Microsoft is not the only company guilty of selling boxed paper and air: Another example is Apple and their MobileMe service, which is also available in box form at Apple Stores everywhere. Shame on them. [Aeroxperience]
