My 2 cents:
- I prefer "phone" over "handset" as I don't like those overly dry formal names that got heavily overloaded with years but still give a false sense of better specificity. - --store is a very counter intuitive name for desktop apps for someone not exposed to the new Windows terminology. Is it intended to mean desktop apps? (some alternatives --desktop, --laptop, --fullsize, --largescreen ?) - --phone vs --type=phone - either seems fine to me and pretty easy to implement. - --target=X is unrelated, it's not for selecting a type of device but for explicitly choosing the device to use if several are connected to your dev station.
