Hey guys, i'm about to buy my first mac, beign a macbook. Now i'm not a power user an almos never create DVD's. Now i dont know if i should buy the 2.0 ghz model with the superdrive or stay with the base system and save the 200 for 2gigs of ram. I ussually do work in office and browse a lot the internet doing research as I'm a biology major, any suggestions on what to do. Is the 0.17 ghz be really that different?
