I just ordered this laptop case in the denim color in the large size for my 15" macbook pro. It is definitely too large, and I have a feeling that the small size would not have fit my computer. Either way, I'll stick with the larger size... and let there be a bit of extra room. The color is much darker than I had anticipated, and the case overall looks very very manly. I guess I can deal with that too. It seems as though there is definitely enough cushion to protect the laptop and that's all I was really after with this purchase. Next time I'll spend a little more and get something nicer looking that actually is made for a 15" computer, though.
I ordered the large size for my 15.5" laptop and it's great.... got it on sale so the price was great. I am in college so i need to carry a laptop a lot and this helps for realsies.... sorry for saying for realsies
