Jane, you need to update the article. In the Surface Pro 2 hands-on video, Marcus says the new Type cover is ALSO 1mm thinner than its predecessor. Which, given the improvements to rigidity and noise, and the fact that it appears to have the same amount of key travel, is pretty sweet.
Although overpriced, they have some incredible accessories for the new Surface tablets.
Yeah they're a bit high. But they're all pretty slick, and the quality of the Surface accessories seems good, and these will likely continue that trend. I especially like that docking station!
It's great that the new covers are backwards compatible with the older models. I imagine a lot of owners of the original Surface Pro will be snagging the new Type Cover. I'd bet that the dock will work with the older model Pro as well.
