Ken has some great points, but is missing the bigger picture. With always on collaboration rooms, such as ones powered by Project Squared, we can define how and where we work. Right now emails, IM's, calls and left voicemails are happening across networks everywhere, each one requiring a specific reaction. With "new way to work" applications, like Project Squared, ALL of those are eliminated. Single pane of glass, truthfully single pane of glass apps allow for easier integration to your teams and less 'fuss' when it comes to simple and natural collaboration. Of course users need to adopt tools like Project Squared, and once they do so 'working' or 'communicating' becomes as natural as being in one conference room together. Couple this with a simple UX, minimalist approach and a cloud first back end, the new way to work is actually obtainable.
