Samsung's rumored 7 inch Galaxy tablet has been spoted in Australia on a commuter train. Testers beware: when you're trying out a prototype in public, be sure you don't have a nosy on looker over your shoulder. We don't know much about this tablet other than that it's 7 inches and is running a version of Android. From what we can see, screen changes are quite responsive. The field tester comments that the Galaxy tablet is "different" to the iPad and that it was "awesome". The device is currently being tested in Australia and is rumored to have an international release to the UK and the US. Take a look at the first hand video and let us know what you think.
