Welcome to 'This day in Engadget', where we crack open the archives and take a whimsical look back at the memories and moments of our storied past. Please join us on this trip down random access memory lane.

If you've not been living under a boulder for the past week or so, you've probably noticed that CES has been going on in glorious, illness-inducing Las Vegas, Nevada. The thing is, Engadget has been running this game for a long, long time, and though historically things are usually wrapping up around the 9th of January every year, the remnants, the wrap-ups, and the gadget hangovers are almost as fun to look back on as the show itself. So, as we wrap up a truly outstanding CES 2011, we thought we'd take a look back at previous CES wrap-ups, some big days, and some downright weird ones, in this nostalgic episode of This day in Engadget.

Back in January of 2005, Engadget was a fairly new site, and it brought its CES coverage to the masses for the first time. As far as we can tell, the entire Engadget team on the ground in Vegas appears to have consisted of Peter Rojas and Ryan Block, and from the looks of it, they were having a pretty good time. By the time January 9th, 2005 rolled around, things were wrapping up so they were able to look fondly back at the week that was, in addition to checking out the Pepper wireless pad, HP's High Def Media Recorder, and Vonage's WiFi phone.

Update: Ryan let us know that the first CES crew actually consisted of himself, Peter, Eric Lin, and Dan Wu.
