After that, the next four slates are all 7 inch models beginning with the the Amazon Kindle Fire and its 7.5% share, the Amazon Kindle Fire HD is next with a 4.9% slice of the pie just beating out the Samsung Galaxy Tab and its 4.8% share. All of the top listed 7 inch tablets on the list sell for less than $200, perhaps explaining why the 7 inch Android niche has been such a popular one. HP is getting into the game with the HP Slate 7 which will be priced at $169.99.
Even non Android manufacturers are turning to the 7 inch screen size for lower priced models. There is the 7.9 inch Apple iPad mini, and there recently has been talk that Microsoft is looking to produce versions of its Microsoft Surface tablet with a 7 inch screen.
