I just bought one of these laptop cases for my 12" PB. I am very impressed with its build quality. A lot of attention to detail. While I haven't tried it with my PB yet, I'm sure its going to work out well. It's custom made to fit Apple laptops. Good cushioning all around. It's really made to be used inside a larger bag, such as a backpack, but does have carry handles and a shoulder strap too. I bought it to use in my backpack. Anyone looking for a small, stylish, well-made laptop sleeve/bag should definately consider Incase.
