I can't continue the setup without using iMessage?
I don't have iMessage, I don't want iMessage. I don't have an iPhone or an iPod touch. When setuping up my new MacBook Air I can't continue without selecting my email address from my iTunes account.
I esspecially don't like the wording of "Let others reach you at:" - I don't want others to reach me by searching for my email address in iMessage.
How do I complete the setup?
MacBook Air, OS X Mountain Lion (10.8)
