Laptops With Adjustable-Height Screens?

You could make laptops more ergonomic if the screens could be raised higher, so you didn't have to look down so much to see them. See the pictures below. I'm wondering whether you can get any laptops with such adjustable-height screens?

Sometime last year I looked into this, but couldn't find anything. Strangely, the only think I managed to find was an online article from some computer publication -- the link for which I've since lost -- from back around 2000, saying that some companies had plans for such laptops. From what I could tell, these designs never appeared.
