That makes sense. From an engineering standpoint, supporting local caching and cloud means they have to write (and maintain, and debug) every algorithm twice. O

That makes sense. From an engineering standpoint, supporting local caching and cloud means they have to write (and maintain, and debug) every algorithm twice. Or, they can write it once to take advantage of the cloud and cross-service integration, and people who don't want that feature-set can use another, less-integrated service. Perhaps they are putting their chips on the assumption that the quality of service that can be provided with data integration is going to exceed alternatives.
