It's not the "same old client/server model" from legacy systems. Essentially it's a publishing model that embraces mobile, cloud and in-memory data computation. ie, real-time data sync and the democratization of data analysis.
Actually, there is one old model that this new model does remind me of: IMAP (and Exchange as well). The e-mail client caches local data, can operate offline and interacts with one server that synchronizes data across multiple clients.
