Finally, my leather book case from PDAir arrived in the mail.

First impression: A nice leather case that allows you to carry around your MBA discretely as a portfolio.
For $99, it delivers what I expected, a leather case that disguises as a book, with a leather wrist pad. The fit as described above by another user is tight but not overly so. The white stitching is subdued. The leather has a stiff shape and provides some padding to the bottom and the top of the case while closed, but does not provide much side protection. The inside of the top lid contains four business card/credit card slots. The case folds shut with a magnetic latch.
Things that bother me a bit: The leather cut out fits the touchpad very closely, but clicking the touchpad takes a little adjusting. Also the leather is not particularly thin on the wrist rest, which affects when I hit the lower keys a bit, especially the arrow keys. However the laptop does close appropriately and goes to sleep when the lid is closed. Also, when closed with the buckle up like a book, the laptop is actually sitting upside down.
I am currently using the laptop for the past hour developing photos, uploading, and the temperature and fan has not increased excessively so. The case itself does not feel like it traps heat excessively.
Let me know if you have any questions!
