I recently returned my 13 inch "Blackbook" and upgraded to a Macbook Pro. I had bought the Speck Products clear acrylic case for my laptop http://www.speckproducts.com/13mac-seethru-ds.html (it's the one on the upper left, the see through case). This case retails for $50 plus shipping, I'd let it go for $20. PM me if you're interested. We can work out PayPal.
