Apple has seen tablet sales decrease rapidly over the last few quarters as Android based devices increased their market share and consumers also opting for larger screen smartphones / phablets such as the Galaxy Note from Samsung.
Apple is following the trend on the smartphone side and is expected to release a 5.5″ version of the iPhone 6 on September 9th.
In addition to that Apple is looking to differentiate and finding ways to increase the tablet sales again. Reports suggest that the company is looking to release a large 12.9″ iPad next year. This could certainly be interesting especially for the business and education segment, which Apple has focused on increasingly in the recent past.
