Im seriously thinking of buying a 15" powerbook for school. this will be my main and only computer. i know this is a pretty powerful machine and could probably handle final cut, but i want to know how well it can handle it. Have any of you used a powerbook for some heavy duty editing??? im definitly going to buy a 15" powerbook because i need the portability for school, but i was also looking at the imacs. how much better does the imac perform in final cut vs. the powerbook?? the powerbook set up im going to have is 1.67 1gb 80gb 128mb vram with final cut express installed. Any advice would be appreciated.
