If you've been waiting with bated breath for Samsung's 56-inch, LED-based DLP HDTV, you need to wait no longer. Samsung has begun to ship this $4,200 set to eager customers all over the world. Being LED-based, the set has a lifespan of 20,000 hours, meaning that the set is only good for 2.28 years of non-stop television. If this doesn't bother you (and unless you leave your TV on nonstop, the lifespan should be a lot longer than 2 years), the HL-S5679W also features 1080p resolution, a 4000:1 contrast ratio, analog and digital tunes, HDMI ports, and energy-saving features. So if you don't mind the limit lifespan, go grab one of these new sets and make your HDTV experience a worthwhile one.
