How do you like it? Does it ever feel like it's running out of juice? I'm planning on getting one pretty soon, mainly for Photoshop, Illustrator and InDesign work. Just wondering if it is capable of doing some fairly complicated graphics work. Wait, what am I talking about. It's a Mac, of course it can. Seriously though, I've heard a few (admittedly very few) complaints about it sometimes lagging and running slow. With 2GB of ram and a Core 2 Duo I wouldn't expect it to run slow though. By the way, what are the speakers like? I like to listen to music when I'm doing my work. Is it worth investing in a good set of headphones?
