There’s no way around it, the name “iPhone 11 Pro Max” is a bit of a mouthful.
The ‘Mac’ at the end is a good descriptor, though. Names come and go. In a year nobody will care.
I remember groaning at “MacBook Pro” in January 2006 when the PowerBook’s successor was unveiled, but now we don’t think twice about it.
Good list of messy product names, though. Personally, I like Mac and Mac Pro, iPad and iPad Pro. iPhone and iPhone Pro, and, Apple Music, Apple Watch, Apple Pay, Apple Card et al.
