The Transformer Prime is styled to match Asus’s latest Ultrabook offerings with a shiny metallic body. The 10.1-inch slate also has a pretty slim keyboard - only 0.33" (8.3mm) - as an added accessory, which adds another 8 hours to the battery life.
Amazon said the Asus Transformer Prime as arriving December 16, and currently on its preorder page it just asks you to sign up to be notified for the arrival. Hopefully the December 8 release date will hold water.
