What's puzzling is that in the "what's in the box" section of the product page, which is where I look for this kind of "gotcha", there is no mention or photo of the stylus being included. I'm sure it is, but it seems like a colossal marketing oversight to not explicitly state that the pen is included in the box. And in the tech specs it states there is support for the surface pen...but again nothing about a pen being part of the tech specs.
