We’ve written about the success of Amazon’s Kindle Fire tablet on multiple occasions. The device is relatively low-powered for an Android-based tablet, but the combination of its low price and the high-profile Amazon and Kindle brand names seems to have made it a rousing success. Last we heard, the heavily modified Android tablet held approximately 40% of the Android tablet market. Fast forward to today–two-and-a-half months later–and a comScore report estimating 54.4% Android tablet market share.

To be fair, comScore’s data is based on web browsing statistics, rather than hard sales figures. But it does give us a good idea of which tablets are being used the most. The second most popular tablet for web browsing, after the Kindle Fire at 54.4%, is Samsung’s Galaxy Tab family at just 15.4%. The rest of the competition fares even worse, with less than 7% usage. Ouch. Google can’t be too happy about these figures either. The search giant makes most of its revenue off of advertising, but Amazon has modified Google’s open-source OS so much that it’s almost completely cut off from Google’s services. As a result, much of the profit Google would have made goes straight into Amazon’s coffers.

Regardless, it’s good to see at least one tablet attempt to take on the iPad, even if its overall sales still pale in comparison. It will be interesting to see how Windows 8 fares when tablets begin running it this fall.
