Hey, I am looking for a little bit of guidance on a purchase I am going to be making. I go to school for Graphic Design, so I use a lot of photoshop. I also do a lot of High Res. image editing, as well as use audio programs for my band. Right now I am a PC user, but I would like to switch over. My problem is I really want the portability of a powerbook, but I know I need a lot of power, which is where the G5 would come in. If I were to buy a maxed out powerbook, would it be a huge difference from a g5? Would I still be able to do what I want on the g4 Powerbook? Would it make more sense to sacrifice the portability and get the extra power? I need some guidance! Please help. -Luke.
