Thank you all for the very interesting responses.
One observation: when you are the first one on and sitting in premium when the rest of the passengers must go through your area: it seems unpleasant to try to read or relax or have conversation since particularly if you seat on the isle far too many persons carrying their briefcases and backpacks, etc will bump may times into you, or even drop things on you as they are bringin in their drinks and or munching on their food.
My observation for plane designers: there should be a separate door or at least immediate turn to one side or the other to designated areas.
