We just got a pretty detailed look at Microsoft's upcoming Dashboard update for the Xbox
, which brings with it the Zune Video Marketplace and Last.fm music streaming, along with Facebook and Twitter social functionality. We were most impressed with Facebook, which includes a feature for spotting which of your Facebook friends have Xbox Live -- a great way to grow that friends list and bring a bit of "synergy" to your life. Last.fm was a bit of a downer, since you can't do anything else while listening to the music, but otherwise there weren't many minuses to the presentation other than the lack of a firm release date.
