So I'm going to college next year and am thinking about a macbook or a macbook air. I know there have been tons of threads like this, but they all care about the optical drive, storage, usb drive, while I don't really care about any of these things. All I care about is the power and portability. So obviously the MBA wins on portability, but is the slow processor noticeable. I could get the MBA cheaper than a new macbook, but if it is a huge step backwards, I don't know if it is worth it. (Right now I have an unstable macbook 2.0 CD with 1 gb ram) I will only be using iTunes, Word, and Safari really nothing too intensive. Thanks!
