I have a PC for gaming, and I'd never in a trillion years buy a mac for gaming(cause that's just stupid, right?). My college major is geographical information systems, and I'm also gonna be taking web design courses(enough to fulfill a certificate, but just using the classes as electives). Looking at the specs, ok yeah, the iMac has the bigger screen(but I have a really nice LCD), it's got a bigger HD(I've got an extra external HD, plus I could always upgrade the HD inside the macbook), and it's got a better GPU. But how much better is the GPU gonna matter running dreamweaver and photoshop? Plus I'll be adding 4gb of aftermarket ram(Samsung or Micron), so I really think the 2.0 SR Macbook with the new X3100 could compete nicely with the low end iMac. The new X3100 uses 144mb of ram, and I figure if I have 4GB of ram plus the X3100, I could even decently run some 3D apps. Plus I have the option to take my work with me on the go should the need ever arise. Am I missing anything else to sway this decision?
