Android 3.1 has arrived on the ASUS Transformer and included is USB host support. Not every tablet has this USB support and to slim the market down even more, the Transformers dock includes two USB2.0 ports. What does this mean? It means that the Transformer now has support for virtually any USB gamepad or accessory.
The ASUSUK Twitter account made a point out of this new function of the Transformer by saying:

This is great for gaming, emulators and such. It also opens new doors for possible Transformer-exclusive gaming.
