I laugh at those who carry around the full foleo case (+ kickstand) + wireless keyboard and dribble over themselves at meetings to tell me how wonderful it is. You've got a 3lb gimped notebook right there.
My iPads wear incipio Feathers and screen protectors, that's it - and it's only a precautionary measure as I know Apple can't make something which actually stands up to daily handling without looking like crud, unlike other makers - especially as I tend to leave toys at home. And on the fairly rare occasions they do venture out, they are in reasonably padded sleeves/compartments.
