Since I broke my laptop, I decided to finally get a Macbook Air 13". I got the maxed-out version with the latest OS.
I am stll exploring it, ran the battery down in suspended mode, since I didn't use it for couple of weeks (super busy with a project at work). I had loaded Win 7 on it also, which is amazing on this machine. Apple has catered to the Win 7 user in many ways with this ultraight, beginning with a special version of Bootcamp for the new Macbook Airs which does all the heavy lifting for you if you want to dual boot with Lion and Win 7. It allows you to create a bootable USB device, downloads all the special MacBook Air drivers for Win 7 and creates a special install partition.
Tonight I am finally using it in the ultimate hipster coffee house. Fun! In windows, two fingers drag down to scroll down, in Lion two fingers drag down to scrolL up

Sweet screen and backlit keyboard!
It fits in my notebook case with my work laptop so I can take it with me to work if I want.
Anyone else get a Sandy Bridge Macbook Air?
