The link will show fresh pictures of the new Text Input Device gathered April 9, 2007. There have been some questions about how it attaches, and how comfortable the controller would be with the keyboard attached. These photos show how that's going to work.
Tony reports that it's hard to tell the difference when it's attached, since your bottom fingers don't actually wrap around the wings of the controller anyway. And it weighs very little, so you barely notice it's there.
By the way, I was told this morning that the keyboard will also ship with a new headset.
