Benchmarks for a mysterious Samsung tablet codenamed the GT-N5100 have surfaced online, sparking speculation that the Korean electronics giant is working on a 7-inch version of the Galaxy Note. The device would fit in nicely between the 5.5-inch Galaxy Note II and the Galaxy Note 10.1, and it would allow Samsung to compete with other tiny tablets like Apple’s iPad mini, Amazon’s Kindle Fire HD, and Google’s Nexus 7.
