The good: Lets you watch your Blu-ray collection on-the-go; HDMI output for use as a standalone player; full access to YouTube and Picasa if connected via Ethernet; comes with cigarette lighter adapter and headrest mount for car use.

The bad: Very expensive, with Blu-ray-equipped laptops available at similar prices; bulky design; short 2.5 hour battery life; small screen limits the capability to see the full detail of Blu-ray; can't output a standard 1080p signal; less reliable playback than standalone players.

The bottom line: The Panasonic DMP-B15 is the world's first portable Blu-ray player and can function as a standalone player too, but ultimately it has too many caveats and costs too much.
