Panasonic Portable Blu

Panasonic showed two new portable Blu-ray players, the 10.1-inch DMP-B500 and the DMP-B100 (shown here). They don't have full HD resolution, but that shouldn't be a negative with such small screen sizes. I want one; they looked better, with a BD disc, than any portable DVD player I've ever seen. The one missing feature is an external video input. Why is that important? The player could then perform double duty as an off-screen monitor for use with a big screen projection system when it isn't needed as a portable device. An OLED display instead of the LCD imaging used here would also be nice, but a $3000 portable OLED Blu-ray player might be a hard sell
