I'm just curious. I need to decide between a MB and an MBP. I can get a refurbished MB with 1 gig of RAM for $1099, but I can get an MBP with 512 MB of RAM for $100 more. The processors (2.0 GHz Intel Core Duo) and hard drive capacity (80 GB) are the same. If I opt for the MacBook, what am I missing out on that I would need a dedicated graphics card for?
