How to connect a USB accessory to an Android smartphone or tablet
With Android 3.1, Google's mobile platform added a new trick to its repertoire – USB host functionality. In plain words, that allows for Android devices to work with a broad range of USB peripherals, such as keyboards, mice, USB flash memory sticks, and even gamepads. But what about smartphones and tablets that don't have a full size USB port? Well, they still can get along well with such accessories too, with the help of an inexpensive gizmo.

The USB On-The-Go cable adapter plugs into the microUSB port of an Android device and provides a standard size USB port on its other end. All you have to do is to plug in the desired USB accessory in there and you should be good to go.

Will Nexus 7 get USB flash drive support via a software update? If I'm not making mistake right now it's possible if rooted. Anyone confirms?
This is the most important factor before buying the Nexus 7 since you don't want to pay $50 more for that extra 8gb. You can easily hook up a flash drive if it supports.

I'm not so sure but i think you wont get the OS updates automatically since this doesn't have to do anything with custom ROMs. And this is the main obstacle preventing me from rooting.
