thanks for adding data points, and one thing i failed to point out is that email is a standard. the standard is what allows different vendors to provide interoperability. so a microsoft exchange server can talk to a mac mail app and mail generated by lotus notes could be stored and processed by gmail. until a standard is created to say what should be included in the "communication tool to supercede email", you're stuck using email and loosely coupled instances of apps x, y, z. it would be pretty hard to get a large company to shift off email, perhaps getting employees onto a social platform in conjunction with email will be a nice transition path. imagine stepping into a new job and on day one getting an email address and a social app ID. i think this could be a big play that could get more and more users off of email, the old way, and onto the new way.
