I'm considering buying a refurb 1.83GHz MBP instead of a BlacBook. One thing that troubles me, though, is the processor speed. I'm pretty sure the 1.83GHz MBP would best the 2.0GHz MB, but I'm looking for reassurance. Will a 1.83GHz MBP be faster than a 2.0GHz MB. I'm thinking it will be because of the dedicated graphics. If it helps, I'll be using the iLife suite, and probably be doing a fair deal of iMovie editing. I won't be using any power applications, I may get Photoshop CS2, but nothing too bad. I'll probably be buying the MBP, the extra screen room is enough for me, but knowing this would really help. Thanks.
