After a week with my new MacBook I decided to set up an iChat account. Checked with the Mac 101 : iChat page here http://support.apple.com/kb/HT2515 followed the onscreen instructions and got an @mac.com account, confirmed with an email from Apple. However. a Mac-based friend has told me that I actually need an @me.com account for iChat. Is this actually true? If so. I'll sign up for the 60-day free trial and take it from there. If I went for a @me.com account, can I delete the @mac.com account from iChat? Thanks for any advice.
