It can manipulate your phone's address book, transfer files, upgrade apps, and receive/send SMS and emails remotely and in real time. Although it's almost functionally indistinguishable from other similar applications, thanks to its B/S architecture, it has no operating system limitations (i.e. it's cross-platform), which is a boon for Mac and Linux users.
