While I was watching the announcement, one of the first things that came to my mind would be my usage of it (if I were to purchase it) in terms of this site. If you don't know already, the iPad has played a large part in the development and the upkeep of this site. However with the Logitech Ultrathin Keyboard Case, I do acknowledge that the keys are somewhat "cramped". I can't even imagine what the experience on the Zaggkeys Mini keyboards would be like.
But then, it would be foolish of me to prejudge something before trying.
