Anyone have a list of items included in the box? I can't seem to find online. I would like to know: 1) Is there a spare pen included in the box? Or there is only 1 stylus? 2) Is there a basic screen protector included? Or I must buy a pack of screen protectors? 3) Is there a pen tether included? 4) Is weight saver module included? 5) Is there any case at all included?
