The Asus Eee Pad Transformer was recently upgraded to Android 3.1; things got a little more interesting because the new version of Google's mobile OS comes with USB host support. Not every Android tablet has them, but the Transformer's keyboard dock thankfully features a pair of USB 2.0 ports.

This theoretically means support for any USB gamepad or accessory. The AsusUK Twitter account made a point to confirm two particularly cool USB controllers the device can now work with:

A French user who goes by the name MrEverblue82 posted a video on YouTube of a PS3 controller lovingly courting the Asus tablet , which we've embedded for you below:

The Eee Pad Transformer sets itself apart from the tablet competition with an optional chiclet-style keyboard dock that essentially transforms the device into a netbook. Besides making the device much more convenient to type on and handle productivity tasks, it also extends battery life from around 9.5 hours to 16 hours thanks to a second battery within. The actual device costs $400 for the 16GB Wi-Fi only model, although the dock will set you back an extra $150.

The Transformer has a 10.1-inch 1280×800 IPS Gorilla Glass capacitive touchscreen display, a 1GHz Nvidia Tegra 2 dual-core processor, 1GB of RAM, 5MP rear and 1.2MP front cameras, a Micro SD expansion slot, and HDMI out. You'll also find speakers and audio jacks, USB 2.0, 802.11b/g/n and Bluetooth 2.1 connectivity, as well as a G-sensor, light sensor, gyroscope, e-compass, and GPS. It also comes with Asus' Waveshare interface, which includes MyNet (streams media to networked devices), MyLibrary (digital bookstore) and MyCloud (cloud storage and remote access tool).
