One of the biggest issues behind 4K TV at the moment is a lack of any 4K broadcasts and 4K physical delivery standards, rendering much of the product's advantages moot and, at the $25,000 Sony's asking for its 4K television, we'd typically to say to any consumer buying one of these devices, silly, silly you.
However, Sony's XBR-84X900 84in 4K TV is a TV with a difference. Details are a little sketchy, with more information to come following Thanksgiving across the pond, however Sony is promising that its product will ship with the first ever 4K content delivery system and will come bundled with Hollywood movies at full native resolution - very interesting.
We would however suggest that, if you're struggling to pay off your mortgage or turned down vacation for some extra pay recently, you may wish to avoid this television, though for the rich looking for as many pixels as they can afford, right now, with real content, this could be the one and, at the very least, Sony's taken a big step in the right direction.
