Creating power out of thin air

Creating power out of thin airFree electricitySmoke and mirrors. Magically creating another 'state' of a material is hogwash.

This particular plasma, the 50-inch PN50A650, was released in the spring of 2008 right around the same time as the slightly less expensive PN50A550, which we reviewed way back then. We really like both of...

It doesn't have the 1080p resolution of higher-priced plasmas, but we didn't really miss that extra detail. What we did miss with this LG, namely deep black levels and more accurate...
