These many people must already know, but I couldn't stop commenting here. Have you seen a laptop inside "My Documents"? that's what ThinkGeek's My Documents Laptop Sleeve does.
The case only supports 15-inch notebooks, but very well made (made of neoprene) and also comes with a pixelated mouse cursor that you can take or move anywhere you want.
It costs $ 30 off. It would be worth a similar Finder, huh?
(Tip from Cybele, thanks!)
