While Samsung has been trying to keep its iPad-challenger, the Samsung Galaxy Tab, under the warps before its forthcoming release, the tablet was earlier this week, filmed by an Australian technology journalist aboard a Sydney train.

According to the detailing of the incident by Electronista.com journalist Sanjiv Sathiah, it was at nearly 8am on Monday morning – at the Central Station - that he filmed the Samsung Galaxy Tab which was in the possession of an unidentified man.

Saying that the chance discovery of the Galaxy Tab was “quite a find,” Sathiah said that he asked the man, armed with the tablet, a number of questions. To Sathiah’s question about whether the man had used the Apple iPad, the man replied in the affirmative and added that the Samsung Galaxy Tab was “very different” from the iPad.

As per Sathiah’s account, the man also said that the Galaxy Tab, which runs the Google Android operating system, was “awesome.” Sathiah said that, off camera, the man denied that he was a Samsung employee. Probably, he was an Australian telco worker, for a company like Optus or Telstra, and was apparently testing the tablet to observe its working on the mobile network “under the tunnels.”

Meanwhile, Samsung has also recently released a sneak peak video of the device on its website – revealing that the Galaxy Tab has a 7-inch LCD screen; 1 GHz processor; GPS; Bluetooth; and Android version 2.2, among some other compelling features.
