With the addition of Art Boards to PSDs the advantages of reviewing a single PSD in browser through CC is less than desirable. In fact it really kind of sucks. I would recommend that Adobe do something to make the reviewing process a little nicer for clients that I'm sharing with and expect comments back. My recommendation is for the browser version of CC recognize the art boards and display them as slides allowing each one to be commented on. And think about how a client that can barely grasp anything technical is supposed to understand what he/she is looking at when it comes to three different views of the same page.
The browser view is not very intuitive when it comes to zooming in and out either.
