Yes I know...
I remember back in the 70's when a stereo system had 50 watts RMS. The Japanese decided that they would invent a new term 'Total Music Power'. They took the 50, multiplied it by 1.7 and then doubled it (because they had 2 speakers). It makes absolutely no technical sense but from a marketing perspective...
Whatever TV you decide to buy you couldn't have picked a better time. The prices have dropped dramatically and with this financial climate there are some great bargains to be had.
