First impressions about SED screens

We've been talking for long now of the third technology for manufacturing big screens, the SED (Surface-conduction Electron-emitter Display).
Canon who's making an expo until tomorrow in Paris-La Défense, demoed a prototype of such a screen. In fact, they put it near a LCD and a Plasma.
Hardware.fr who went to see this screen seem to lack superlatives to describe it. It seems it overcomes by far all those he's compared too (probably not the best in their category though).
The first SED TV sets should be available for buying by the end of the year. One year later, LCD displays following this norm should arrive.
