I have no idea how Panasonic crammed all that into this little package, but they deserve congrats on getting it done. Panasonic also did a great job with the screen. Seven inches is about as much as you could squeeze into such a tiny case and it is fine for close viewing. It's really a one person show, but that's all it should be. The LCD looks pretty good.
Colors are nice, detail is accurate and brightness is acceptable.
You won't feel the LFE on the soundtrack, but you don't need that while traveling. But this thing could certainly be used as a secondary player, in a bedroom or study, while you weren't traveling. Lastly, the LV75 is stunning. The design is such an improvement over Panasonic's older models that it's almost unrecognizable as one of the brand's players. It is also thin as hell.
