Maybe something like;
- Mac, MacBook, iPhone, iPad, Watch
And you can get them in:
- Mini, Max or just "normal size"
With your choice of:
- M?, M? Pro, M? Ultra
Running
- MacOS, iOS, iPadOS, watchOS
We've already got a "mini" iPhone (SE), MacBook (Air), Mac. Plus the normal sized ones; 14" for the laptops and studio for the Mac, and then max being 16" laptops, or a tower mac, and the 12.9" tablet etc. Same for the watch too, and the iMac has played around the 21/24/27 sizes already.
Perhaps I just don't understand the product differential requirements from branding / marketing perspectives.
