With the volume of posts in this thread it's difficult to tell whether this issue has come up before, but in case it hasn't, I've found that 1A can be somewhat undesirable for overnight flights. Even when the curtain is drawn, light from the galley has a nasty habit of spilling into the pod, and unfortunately the seat is aligned so that spillage is directly in line with the headrest. Obviously not a major issue, but I don't use the eyemask and so the constant illumination made it difficult to sleep.
