Long time lurker, 1st time poster. I know this has been asked but I haven't seen how capable the models are of running Logic and Final Cut be addressed. Like many here I've been holding out for the new MBPs, but now that the 13" still has a Core 2 Duo I'm torn on which one I need. If they'd stuck the i3 in the 13" it would be a no brainer, but now I am debating between the 13" and 15" models. I use my computer every day several hours a day, it's a big part of my life. Besides internet and email, I mostly use the iLife suite (iWeb for my website, iPhoto for my photos, iTunes for my music, etc.) but I also do a lot of recording in Logic Express and video editing in Final Cut Express. I like the portability, extended battery life, and reduced weight of the 13" model, but I want to make sure it would be able to handle the video and audio editing I spend a lot of time doing. So which one should I go with? If I get the 13" it will definitely be fully loaded with the 8GB RAM, faster CPU, and larger hard drive. As far as the 15", I have no idea which model would I need. Would one of the cheaper 15" models do all I need it to do, or do I need to get some upgrades to make sure it will run Final Cut and Logic as smoothly as possible? Do I need 8GB ram for this stuff? Any help is much appreciated, thanks.
