Surface Pro 3 lap usage?

That is a pretty **** comment. 1) It's a valid question. The Surface 3 or 4 does not work well in your lap because the stand doesn't work well that way, so it closes up. 2) I think you mean it conflicts with the Surface "Book" concept. 3) I have both the Surface PRO and Surface Book and I can confirm the Surface does not work well on your lap. You would need a 3rd party case that can keep the screen vertical without relying on the built-in stand.
