LATEST ADDITIONS

CES doesn't officially open until Thursday, January 6, but for the horde of assembled press, it begins on January 5. While workers swarm over the Las Vegas Nevada convention center in what appears to be a hopeless attempt to have everything ready by Thursday's official opening, wall-to-wall press conferences are being held. Tolerated as a necessary chore by the scribes, the press conferences nevertheless serve a useful purpose for manufacturers, giving them a captive audience to do with as they will. This year the festivities were more efficiently organized than usual, the only shortcoming being the lack of sufficient pauses between events.

Here's something that won't be at CES this week, but could well appear at the show in years to come. Researchers at the University of Cambridge in England are working on a new video-projection technology based on holographic techniques. Now, don't get too excited; the images are 2-dimensional, not 3-D. But the technology is plenty interesting nonetheless.

Whether it's because of newspaper ads, TV shows saying they're being broadcast in HDTV, or the buzz from co-workers, relatives, and friends, you've probably been thinking about testing the HDTV waters. And now is a great time to buy a high-definition set.
