The new portable iPad keyboard from Logitech seems like a pretty nice keyboard. Pity there's no way to connect it to your iPad while traveling. I can't see myself carrying to items while on the road. If I were to be traveling light like the people in the promo video, I'd just carry the iPad and nothing else.
Compare this to the Surface's cover with built-in keyboard. It is one of the only things I really like about the Surface. Every tablet needs a cover, and for the occassions where a keyboard is needed, you're already carrying one with you.
But since I switched back to a bigger iPad Air, I don't feel the need for a tactile keyboard anymore. Typing on the bigger display is just as comfortable, and doesn't feel cramped or forced in any way.
