Prototype Sony Blu-ray player

Originally, a big selling point for Blu-ray was that it would arrive as a complete system - that is, the first units would both record and play high-definition DVDs. Nervous Hollywood studios seem to have put the kibosh on that, at least for the moment, as no such combo devices were announced as standalone models.

LGs FM30 (bottom) and JM53 hard-disk portable movie players have 1.8-inch OLED screens.

Sony's new 55-inch, 1080p SXRD rear-projection HDTV is 30 percent thinner than earlier models.
