I don’t know of any slim Blu Ray Burners that are available to the general public yet. You can buy an entire laptop with a Blu Ray burner included—Dell has one for under $1000 from what I’ve read, called the Inspiron 1525. But you are a little early for notebook Blu Ray burners in the retail channel.
There is an LG external Blu Ray burner that can hook up to your laptop via usb. http://www.newegg.com/Product/Product.aspx?Item=N82E16827136150 But that may be a bit clumsy for you.
