According to some recent leaks, Apple may resurrect the iPad Mini name this year. A new post on MacOtakara has suggested that this tablet may be even more budget-friendly than usual. It claims that the 5th generation of the device could use the A10 Fusion - the chipset found in the iPhone 7.

The A10X is by no means outdated, it's still faster than every single chipset that's made it to Android tablets. The main reason I bought an IPP is that it's genuinely high end, in terms of screen, speakers, performance, and battery life. Don't know about upgrading though considering the removal of the 3.5mm jack and the new bendgate.
