How does Android handle tablet specific apps and how do you distinguish these apps? I know there are Android apps that only work on Tablet devices (they say there are currently 16) and wont work on phones. There is a similar relationship between the iPad and iPhone but in the iTunes app store there are distinct iPad and iPhone tabs. There doesn't appear to be the same type of distinction in the Android Market that will allow me to browse Tablet specific apps.
