In 2007, Amazon has released Kindle ebook reader, and until October of 2009, Barno launched its eBook reader, Nook. But this time Barno seized opportunities quickly from the e-reading market transition to the Tablet market, Barno released 7-inch flat-screen Nook Color that is adopted with Android2.2 preinstalled system in November 2010.
