Okay so i am new to this whole mac craze and i guess i am jumping on the bandwagon here, I am looking for a laptop my friend just got a mac book pro for college and he says it is amazing... now i have been looking at the macs and i have been checking out the black mac book, with the 2GB 667 DDR2 SDRAM - 2x1GB memory and 2GB 667 DDR2 SDRAM - 2x1GB hard drive and i am wondering if it is worth stepping up to the mac book pro 15" for $600 more?
