The docking station/audio dock now appears in a full hands-on demo on YouTube, and while we don’t have any news except for what you can see, it would definitely make for a great companion to the compact tablet.
The case is apparently sold in a store called Yodobashi Camera somewhere in Japan, and the person who bought it got a chance to purchase it a day prior to mass release.
Sadly, it’s not yet clear whether it will come to the United States, and outside of Asia. It’s not mentioned anywhere on the official Asus America webpage. We’d keep our fingers crossed, though.
