I am looking at purchasing my first macbook. I will be using it primarily for web design using Adobe CS3 and video editing. I am going to hook it up to a monitor most of the time. Here are my questions? 1) The purchase will be replacing my current desktop. I have always used a desktop for my web projects. Will the MBP be a better desktop replacement vs. the new imac? 2) For Adobe CS3 and some video editing, should I go with the 256mb video card, or will the 128mb be good enough? What about the hard drive speed? Thanks!
