Apple's upcoming 9.7-inch iPad Pro is not only a tablet that consumers are looking forward to getting their hands on, but also one that Apple believes could potentially reignite the dwindling passion that has recently seeped out of the tablet market. Early speculation suggested that the hardware could be ultimately comparable to the existing 12.9-inch iPad Pro in terms of functionality, but it's now being suggested that there could be one key difference other than form factor; the camera sensor that ships with the tablet.
