On June 11, 2009, I lost a cherished friend: the Sony Watchman TV I'd owned for 20 years. When analog TV broadcasts went dead that day, my Watchman, along with every other portable analog mini-TV, suddenly became useless. A few portable digital TVs have since appeared to fill the gap, but because the ATSC digital-TV standard wasn't designed for mobile use, none of them can deliver the reliable roving reception of my 1980s-vintage Watchman.

Electronics engineers prize the LED for its brightness and cool-running efficiency. Environmentalists and utility companies tout its low power consumption. Videophiles are warming to it for the performance enhancements it facilitates.
