I know that this is a bit off of the "Developer/Architect" focus of our blog site, but if you want to see some interesting new technologies from Microsoft, check out the Microsoft @ CES site: http://microsoftatces.com/.
At the moment they have the Bill Gates Keynote uploaded and they also have something that I am very interested in: The upcoming Microsoft "Home" Server. A nice central location to store all of your files (pictures, video, maybe even Recorded content for you Media Center fans), without the administration overhead of a Windows Server. It has web accessible Remote Desktop and easy access from the XBox. What more can you ask for? Don't answer that! :)
Oh, and don't forget to check out the Mass Effect Game walkthrough (at the bottom of the list). It looks like it's going to be a phenomenal game, and the graphics are so..."Choice" to use a phrase from the 80's! I just hope it comes out on the PC as well as the XBox. They also have Halo 3, and Gears of War links.
