We still remember the halcyon days of 2005 when we first laid eyes upon your black as a CRT / thin as a plasma or LCD self, and equally recognize the pain of each false start and delay that followed, each leading up to today's announcement by Canon that it is abandoning SED HDTVs entirely. It had held out hope as late as last spring that the technology could have a future in professional displays, but Japan's The Nikkei reports it simply couldn't bring down costs enough.
