Alright, Im going to buying a Mac laptop soon. However still torn between a PowerBook and an iBook... I was wondering if there would be any noticeable difference in speed between the two. The applications I plan on using are, Word, Powerpoint, AIM, and probably watching videos (either divx or straight off a DVD). Would the iBook be able to handle all those applications running all at once? If I do get the iBook I would probably add an additional 256mb of RAM into it. Also is the iBook outter construction durable as the outter casing of the powerbook?
