Like they do every year, Engadget is back with its obsessive technology coverage from the big CES trade show in Las Vegas. You can follow along with all the insanity at the optimized ces.engadget.com or at engadget.com/tag/ces/. CES officially runs from January 7-10, 2010, but there have already been a ton of posts. Other big tech blogs covering CES include, Gizmodo, gdgt, and Boy Genius Report (just to name a very few).
