>Samsung logo removed.
Did they? A quick browse through Google image search shows lots of Tab 10.1 pictures, many with a Samsung logo and many without (here for example: http://popherald.com/samsung-galaxy-tab-honeycomb-release-da...).
Most of the pics without a logo seem to be pre-release marketing photos. I wonder if the Apple submittal grabbed a marketing photo someplace. We shall soon see.
