hello! i am new to this forum and to macs. i am planning on purchasing a mac just for a change. i am a film student and i hope to get a notebook for class. i don't expect to do all my video editing on it (since school has the equipments), but i do expect to do a little editing myself for practice/fun/projects. i am currently on a budget. i would love to get a powerbook but it seems like an iBook is more affordable. i was thinking of getting a cheaper G5 desktop but i think a portable laptop would work better for me because i am also a psych double major and i bring my computer to class from time to time. is ibook capable for adequate video editing? it looks really nice. also, is 1.2/1.33 gHz fast? how fast is it comparing to p3 and p4? i am computer illiterate. i wanna learn more. i am sorry if this question has been asked before. thanks!
