I could use your advice on something that could help me decide if I want a Macbook Air or not. The Macbook Air only has an 80gb hard drive, and therefore it is not really meant to be the home to your full iTunes library. When you have a wireless connection, you can probably use "Back to my Mac" to access your iTunes library on your iMac or Mac Mini back at home. (Any better ways that you know of?) However, when you are on a plane or otherwise don't have access to the internet, how do you plan to access iTunes videos and music? Is there any way to treat the Macbook Air like an iPod and have it sync to iTunes and copy whatever content to tell it to? If you cannot use the Macbook Air as a secondary machine to access your iTunes content while offline, that is a major problem for me!
