I am a student so I work a lot with word processing and other programs such as Photoshop. But I also do a lot of the usual internet and e-mail. I do work with video and music editing but not much. I wanted to know if there is a noticeable difference between the 2.0 and 2,4 GHz aluminum Macbooks. I am currently on a 2.4GHz iMac so but I wanted something portable as well. Also in this debate is the 2.4 GHz Blackbook, but I find it will soon be outdated. What do you think?
