Hi, I'm thinking about getting a macbook air. I might even wait for the revision 2. Right now I have a Dell PC with an Intel Pentium 4 2.4ghz processor and 1.25 gb of ram. I have 2 questions. How would a 1.6 Core 2 Duo macbook air compare to the speed of my older Dell. Another question... How would I transfer my iTunes to my new air. Thanks for helping a newbie.
