While the brief maintenance-related outage didn't result in new updates for Xbox Live or Zune, Xbox.com's MyXbox page got a nice little aesthetic overhaul. The new design gives your avatar more prominence as well as offering faster access to stats.
The new, much sleeker MyXbox page offers quicker access to achievements, recently viewed friends, recently played games, and the like, through a nice highlighted menu. Basically, it's looking more and more like the Xbox's Dashboard, which we're sure is intentional. Go check it out if you're an Xbox Live user.
