From day one, users have wanted to add a keyboard to the iPad in an effort to try to replace their notebooks with the super small and light iPad. This iPad "cover" is the closest thing I have seen yet that will add a keyboard to your iPad while retaining the beauty of the design.
It is from Logitech, will be $99, and is expected to start shipping in 2 to 4 weeks. From the video it looks like it doubles the thickness of the iPad, but still looks very sleek. I don't need a keyboard very often, so normally just have my iPad and take the Orgami workstation with me when/if I think I will need a keyboard. I am not sure what you would do with this "cover" when you did not want to use it as it does not look like it folds around the back?
