According to the latest statistics released by ComScore, the Android tablet arena is now being dominated by online retail biggie Amazon, with the company's aggressively-priced 7-inch Kindle Fire tablet holding nearly 55 percent of the market share by February this year.

In spite of reports that Kindle Fire sales had started plunging at the beginning of 2012, the ComScore data has revealed that the Amazon tablet dominated the Android tablet market with a nearly 30 percent share in December

Comscore has revealed that the Android smartphones have registered increasing sales between February and May 2010, while the sales of Microsoft, Apple, Palm and Research in Motion have declined in this period.

However, the figures for this quarter will be different, as it has witnessed the launch of iPhone 4 and other Android phones.

The latest data from Comscore reveals that in the three-month period between February and May 2010, Android was the only smartphone operating system, which saw an increase in the market share.
