Okay, I was able to get through Christmas without spending any of the 3k I saved for my new iMac. I was sure there would some mention of an upgrade at MacWorld but there wasn't. Should I buy now or continue to wait it out? When is the next Mac event where there might be an upgrade mentioned? The last time I opted not to wait, I bought the 15"powerbook I'm using now, instead of the intel MacBook Pro that came out a month later.
