I agree with Florux, Cindit0 and jelake. The multiple email address feature would make this tool useable for me vs. frustrating. I am a new user and love the potential for this tool to organize my life, but creating multiple accounts to separate out personal and professional is just cumbersome and changing an email address constantly is equally cumbersome. This is a tool that seems at a very basic level to promote easy, streamlined organization. The single email account prevents Evernote from meeting my needs as a user.
