Samsung Galaxy Tab (2010)
Introduced in Sept. 2010, the Samsung Galaxy Tab was one of the first Android devices released post-iPad. With its 7-inch screen, the Galaxy Tab was smaller than the iPad and could be held comfortably in one hand. But this iPad counter-programming feature wasn't enough to give the Galaxy Tab much headway. Its size, however, was an influence on the more successful 7-inch tablets to come such as the Amazon Kindle Fire and Google Nexus 7.
