I like it.  I agree with everything in the above statement, but, it's those damn technical details...

• It can be anonymous, but only if you know what you're doing.
• It is secure and easy to use, but not easy to use securely.
• It's a fast compared to international wire transfers, but too slow for day-to-day use. (e.g., 10-60 minutes is too long to wait for a burger).
• It can't be accepted where there is no internet connection, or where people have no clue.

All of these things can and will be fixed; I just feel that it is important to be careful at this early stage, when talking about ways to "let the world know" about bitcoin, not to make it sound better than it is (yet).  It could be quite bad for public confidence if there was for example a wave of adoption followed by a wave of wallet theft due to ignorance...

How about:

"Bitcoin.  You're not ready."
"Bitcoin is a doorway; your mind is the only key."
"It is like a finger pointing at a coin..."
"Bitcoin is awesome but you totally wouldn't get it."
