The site as a whole got a visual overhaul, actually, but what established Dropbox users are going to most appreciate is the ability to create new ZIP-ed packages of different files—a few files, one or two folders, and maybe that picture, all at once—and grab them. The Dropbox team also added a search bar and "Gmail-style keyboard shortcuts," although we haven't seen a guide to those shortcuts as of yet.
The non-iPhone mobile version, assuming I'm seeing it on my Android model, works fairly well, providing quick access to files and recent changes. We're still waiting on a dedicated iPhone app—submitted for Apple's approval about four weeks ago—but these changes, mobile and otherwise, are a nice step forward for grabbing files when you're at a non-synced computer or on your mobile device.
