I'm getting an Ibook next week! I'm switching from PC to Mac. I can't decide whether to spend the extra $250 on the 14" or not. The 14" has two advantages to the 12" as I see it 1) the screen is bigger (even though the resolution is the same) and 2) it is a faster processor. How much of a difference does the 1.33 processor make than the 1.2? The biggest strain I'll be putting on this computer is multitrack audio recording from an 8 input Presonus Firepod using Cubase LE software. I won't be using too many VST instruments. I'll also be doing a lot of web design, and some minor photoshop stuff. Thanks for your help!
