I'm curious particularly with iPod Touch and iPad Mini
The plural would be iPod Touches and iPad Minis, or iPods Touch and iPads Mini
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Touches and Minis. Not iPads Touch or iPads Mini. The plural is generally formed with an entire brand and model name. Compare Chevrolet Impalas (not Chevrolets Impala).
