If you believe AuthenTec the best feature of the LG eXpo is not its Snapdragon processor, but the fingerprint reader ensconced below its screen.
The above 3 minute video takes us through its various functions, and it does seem like a useful piece of kit. In my experience with fingerprint sensors however it is usually not as smooth as easy as they make it out to be, but who knows, they may have gotten it right this time.
Of note is that this video shows the screen rotating while in the browser, confirming yet again the device does come with an accelerometer.
The LG eXpo should be available today in AT&T stores.
