I just sold my powerbook and am thinking about getting a macbook, problem is the macbook won't run FCP but it will run FCE. My question is, will my older FCP4 files be able to open in FCE and when the time comes for me to get a mac pro and FCP will the FCE projects open in FCP? I'm assuming that once opened in FCP5 the files would no longer work in FCE if they are in fact compatible. I would just eliminate the problem and get a 15" MBP, but I want the smaller size of the 13" macbook. I'm thinking I may just have to bite the bullet and get a MBP. grr. I wish there was a smaller MBP. In case this has been answered before I did search the forums, and found nothing related to this specific topic.
