TAKEAWAY: Joshua Greenbaum writes of an apparent trend to what might eventually be SaaS 2.0 -- the appearance of value-added SaaS applications. He suggests that the SaaS market is divided into pure-play alternatives to on-premise software but also a new category of services that are impossible to replicate via on-premise software.
Greenbaum cites some specific examples -- GT Nexus offers aggregated information from multiple sources alongside its service. He also predicts that pure-play SaaS without value-adds will also succumb ultimately to commodity pricing models as value-added SaaS becomes more prevalent.
