Hey all, I'm going to buy a macbook in a couple days and I'm trying to make an informed decision between the 2.0 and 2.4 aluminum rigs. For those with the 2.0 model, could you list software and tasks (if any) that slow your laptop down? How does the 2.0 handle streaming HD content? Playing HD videos? Does encoding videos with Handbrake slow it down? How is Photoshop on it? I know Flash is CPU intensive, is anything else surprisingly taxing on the processor? I know that was a lot of questions, thanks in advance for your answers and helping me make my decision!
