Use the Nexus 10 to simulate almost any Android device while

We've all heard the stories that say it's impossible to develop for Android because of all the different possible screen sizes and resolutions. The flip side is that the way Android development is done, most of the time that doesn't really matter. I'm able to string together an Android application, but I'm no serious app developer, so I'm guessing the reality lies somewhere in the middle -- having a selection of screen sizes and resolutions to test on can;t be a bad thing.
