Its finally time to upgrade the old 12" PowerBook and I'm looking at the MacBook as a replacement. The biggest difference for me between the 2 white models is the processing speed. The 120GB Hard Drive will be plenty (actually, I MIGHT upgrade either one to a 250GB), and the SuperDrive on the higher end machine isn't worth a lot to me, I have an iMac with a SuperDrive, so any burning I need to do will be on it...I just don't burn stuff on my laptops. And either one I would do an after-market upgrade to 4GB of RAM. The main stuff I'd do on it will be Photoshop, Lightroom and Dreamweaver. I'd love to have a MacBook Pro, but I just can't do that much $$. So, do you think I'd see that much difference in the speed between the 2 systems (2.1Ghz vs 2.4Ghz?). Keep in mind my iMac (1st version Alu.) is a 2.0Ghz with 4GB RAM and to me, it is VERY FAST (compared to my PCs they make me use at work!) Thanks for your opinions!
