I was on the recent Edge TA and would avoid booking an Edge Class ship in the future. We did like the infinite veranda - put the window all the way down and much like a balcony. And, since it wasn't hot (didn't need AC), we could put the window down a bit at night to listen to the sea.
I missed the promenade for walking that most older ships have, although the walking track on the Edge was nicer than expected. I liked the way it double looped around through 2 decks, giving you a hill.
Hated the rooftop "movie" theatre. Not enough seating and couldn't use when raining. Would prefer an actual theatre or something indoors for movies.
Too many speciality dining restaurants taking up too much space. And as others have noted - does the few # of people buying top end designer watches, other jewelry and handbags justify the space involved?
And, no place to view from the front of the ship unless you wanted to go to gym.
