Those who believe Google Android products are cheap knockoffs of Apple's iPhone and iPad were given more ammo this week when it emerged that Samsung hired the same child actress as Apple to star in the ads for its new tablet.

Separately, Google was forced to pull a voice control app called "Siri" from the Android market after complaints the clone software was trying to masquerade as an official port of the Siri feature on the iPhone 4S.

Buoyed by recent successes in court in its war with Apple, sparked after Apple claimed Samsung's Galaxy Tab "slavishly copied" the iPad, Samsung has become ever more confrontational in its advertising.

The South Korean consumer electronics giant - now the number one smartphone maker in Australia, according to IDC - released two ads for its Galaxy S II smartphone that launched thinly veiled attacks on Apple products and ridiculed the hordes who line up for days to buy them.
