Is there more to it, than just upgrading to the 1.6 processor and 4gb ram? I apologize if I sound ignorant..... I am completely new to Mac.... just decided to make the swtch and I am getting the 11" Air. I have been reading these forums to help me make a decision! I want the most efficient verison of the 11" MBA. I thought about going with the 13", however...... it was a lot bigger than what I wanted. I like how small the 11" is... I am a student and will be taking it everywhere.
