Previously, Kotaku posted a comparison between the original PS Vita and the new, slimmer PS Vita. You might have seen it. But that was just a photo and didn't move. Now, there's a video. It moves.
In the video, the original Vita is stacked on top of the new revamped Vita. Stick around to 2:50 minutes in to see how the screens look from the side. Yes, the side!
