I'm just back from a trip in Europe and I have a question concerning the impending update of the MacPro line. I was jetlagged but I read a post from someone who argued passionately that the MacPro line had now fallen behind the MacBook Pro and that Apple couldn't possibly hold off on upgrading this line until the Fall. Here's my question: how does the current MacPro line suffer in comparison to the MacBook Pros and do you think that this will prompt a refresh of the line in July/August?
