I’ve updated my Xbox360 with New Xbox Experience (NXE), the newest Xbox360 dashboard, smiliar to PS3 XMB with avatar inside. This latest installament provide you to copy your full dvd game into Xbox360 HDD, that makes you can play game with faster loading than usual,but you still have to insert those DVD games if you want to play. Another feature you will see Xbox360 avatar, an avatar about your own profile (similar like Mii in Wii), that you can make your own character, or sometimes you make character that similar to the owner. (like myself, lol)
Xbox360 NXE update is very brilliant idea, especially with HDD games install. I like a lot this feature, because some games really have loooong loading to play.
And FYI, in this December, microsoft also give NXE updated avatar for winter outfits, and you will get it automatically if you just signed in to XBOX LIVE. (very quick update, I even don’t realize)
Now, here’s my own gamertag
