Apple

Disagree. Apple has very high standards and on a more performance level they need to outstrip or be at level with Qualcomm modems.

Intel modems were inferior in every way to Qualcomm, so developing them to even match QC with their thousands of patents is not an easy feat.

ARM processors I dare say are something more feasible to develop, as the architecture itself already lends its benefits to the company developing it versus x86.

I do see Apple attempting this again in the near future though, but only when there is a more realistic opportunity.
