I agree on the poor layout and the exorbitant cost -- those things won't change. Disney charges what it does because it can get it.
But everyone is missing the biggie that comes with Concierge ...
(1) the ability to book a Cabana at Castaway Cay before everyone else [there's only 21 available];
(2) the ability to book Palo/Remy before everyone else; and other privileges include the ability to choose where you sit in the dining areas, who you sit with, as well as choose the rotation you desire. As mentioned before, the Lounge on the Dream and Private Sun Deck look like a lot of fun (and look very, very relaxing). We've not been on a
Disney cruise yet, but aren't expecting to receive the Adult perks like we have on Norwegian, Princess, or RCCL ... but we have a little more room than standard cabins, AND we got a Cabana, AND we have the option to have any MDR food for room service, including hot breakfasts ... all of this in addition to everything else mentioned in this thread.
Dream: Concierge One-Bedroom Suite with Verandah (Category T) 536 square feet, sleeps 5. Queen-size bed, living area with double convertible sofa, Murphy bed "in some," walk-in closet, whirlpool bathtub, rain shower, private verandah, concierge service. 11th and 12th Decks. We lose over 75 square feet from the classic ships, but we gain a private lounge, and a private Sun Deck. I'm very okay with that.
Magic: Concierge One-Bedroom Suite with Verandah (Category T) 614 square feet, sleeps 5. Queen-size bed, living area with double convertible sofa, Murphy bed, walk-in closet, whirlpool bathtub, rain shower, private verandah, concierge service. 8th Deck.
