I do if i dont have wireless dongle fitted to my pc.... For me to preview on my Tablet it runs through my router and then send it to my tablet.
There's nothing to install to run via usb, ADB can be in the C2 Directory and is Free, All android devices have ADB Client installed as part of the OS that makes it easy for them to push, retrieve and run files via USB.
I just thought it would another option for end users to test games that would require a very small amount of code from your side.
Other wise i have to go and use Phonegap/appmobi, or Cocoon apps to complie, then copy the APK file to my tablet just to check a small change.
