I would really like to buy the 11 inch Macbook Air tomorrow if upgraded models are released. I am currently on a late 2008 13" 2.4 Ghz Unibody Macbook. These are my questions: 1) Will the upgraded 11 inch ram model with a faster processor (both features customizable online which are currently 4 GB and 1.6 Ghz) be available for purchase in the store? This is assuming a similar upgrade situation. 2) How quickly do newly released laptops sell out in-store and online on the first day they are available? 3) How bad are the graphics compared to the late 2008 macbooks? Thank you! Let's all hope tomorrow is a success for us.
