I agree, in terms of convenience for higher-end shopping it's nice. I'm more concerned about the erosion of true public space (as in a public plaza, square, city streets, etc) and the conflation of such space with purely commercial zones. I know of at least one dense "new urban" development (University Villages in Marina, CA) that includes a plaza owned by the developer, which allows them to outright ban people, demonstrations, gatherings, or at the very least make it prohibitively restrictive when trying to plan or hold such events.

As a shopping mall, it's great. As a neighborhood, which it certainly aspires to, it sucks.
