With all the noise of the latest MB changes, I haven't been able to see a straight answer regarding this question. Regardless of what I replace my 12" PB with, and whether I continue using my FW miniDV camera or a newer HDD HiDef one, I still have a choice of doing the import on my iMac at home. So I can "survive" without the FW on a MacBook for doing the initial import for the video. My concern is about the editing process. I currently use external FW400 7200RPM drives to store the video project files for editing. If I go with a MB and USB2.0 only, will I still be able to perform that editing without issues? will the through-put and speed of the drive be bad enough compared to FW that it is not worth it? Thank you.
