Google has now come in direct completion with Apple, Amazon and Microsoft with the launch of its first own-branded tablet computer called the Nexus 7.

This Seven-inch tablet has been built around its very own Android in partnership with Taiwanese manufacturer Asus. It’s the same company behind another Android tablet, the Transformer Prime.

The announcement came at Google's I/O developer conference in California. The tablet is priced at $199 (£127); Google's Nexus 7 is both more affordable and physically smaller than many of its rivals. It has a 1.2-megapixel camera and is available with 8GB of memory (£159) or 16GB (£199).

According to the company officials this tab is a "serious gaming device" and its small size is ideal for emailing, browsing the web and downloading applications, which certainly gives it a much broader TG band than many others in the same league.

Last week Microsoft also announced that it would be offering its own tablet, called Surface, which will run on its next Windows 8 operating system, but it would not be released before this autumn.

Keeping the memory offered and camera quality aside, Nexus 7 focuses mostly on content like the Kindle Fire.

As soon as the device boots up, you get recommendations for music, movies, magazines, books, etc. For which Google locked down deals with major movie and TV studios. Also it is extremely well built.

It has got a rubbery back which makes the Nexus 7 easy to grip unlike many other Android tabs which are available in the market.

The tablet from the search engine giant comes with its new Android Jelly Bean, the next version of Google's mobile operating system. Jelly Bean is a minor upgrade to the last version, called Ice Cream Sandwich, so the look and feel is pretty much the same. Jellybean is Android's fastest mobile operating system till date.

The tab also has a Siri-like companion that uses the power of Google to come up for the answer you're looking for. They surely didn’t have to work too hard to come up with this feature though.

The tablet-PC market is indeed growing and set for an explosive growth across the globe in coming years.

Total sales of tablet computers will reach 105m units this year and 143m in 2013, according to the research firm IDC, published in The Guardian, compared with total PC sales of about 400m, of which more than 60% will be laptops.

Apple is expected to remain the dominant player in the tablet market for the foreseeable future, with Gartner forecasting that the iPad will account for 61.4% of all sales this year. Android tablets which include a variety of manufacturers, including Sony and Motorola – are forecast to account for 31.9% of tablet computer sales this year.

Considering the Indian market, Apple’s iPad has managed to maintain its premier position in the Indian market with 51% market share. Samsung’s achievement at extending its success in the handset segment to the tablet segment, with its Galaxy Tab, allowed Samsung to occupy the second spot with 24% market share. Indian consumers also showed a strong penchant for RIM’s BlackBerry PlayBook after prices were slashed significantly, making it the third largest player with a 10.4% market share.

Let see how the Indian consumers will react to this newly launched Google’s Nexus 7,( though the release date in India is still a question) and the upcoming Microsoft’s Surface.
