Well, as one piece of data, I certainly mean the system, rather than any one client, when I say "email." When I say "email me," I don't mean "make something show up in gmail," I mean, send me a message over the email protocol. I don't use email as a to-do list. I use it for correspondence, often with people who use other clients. My conception of email is client-agnostic, and I think almost everyone I deal with (admittedly outside of the tech/valley/startup inside) thinks of it the same way. I hear things like "I'll shoot you an email," or "I need to check my email," or "what program do you use for email?", none of which imply that the speaker intends to be talking about an app. Texting isn't an app, the telephone isn't an app, email isn't an app, at least for many people.
