However, research firm Ovum, claims that Google has not solved the biggest challenge for Android and that it still has significant challenges across its device portfolio which it is far from solving.

Ovum chief telecoms analyst, Jan Dawson, said though the Nexus 7 borrows heavily from the Amazon Kindle Fire in that it puts content front and centre, it lacks compelling apps and content optimised for the larger screen size.

"At seven inches, this problem is less acute, but it doesn't solve the problem and Google said nothing about how it will address this problem," he said.

In addition, Dawson said the price point of the tablet is not sustainable in the long-term as it likely benefits from some subsidy.

"But the tablet is an important step forward for Google's Android tablet strategy, in that it breaks the dichotomy that exists presently between low-priced, low performance devices and over-priced, high spec devices," he said.
