Just wanted to write a follow-up.
I received the laptop and it's blazingly fast. It's incredibly thin too.
I actually got several compliments at school.
1. Unfortunately for me though, the color gamut is really off for it to be my primary machine.
2. Also my unit had unacceptable amount of uneven lighting on the bottom.
So, for these reasons I decided to return it and buy a 2011 MBP 15.
I have been using MBP 15s for a while , so I got used to their suburb displays I guess.
What interested me in MBA was the resolution , which is the same as 15 inch MBP, unfortunately thinness comes at a price of poor display quality. Another thing, I didn't like in MBA was the creaking, every time I picked it up, but that might not be problem with all MBAs
