That would be sad if why. Apple was really late to the mp3 player game with the iPod, but if you're Apple, it's not about when you do it but that you do it really well. See also: iPhone.
But Apple also sometimes does "hobby" projects like Apple TV.
(Personally I kind of wish they'd sell an Apple TV gaming configuration with a decent controller included in the box and maybe a full year's subscription to Apple Arcade.)
The iPhone combined music player, mobile internet device and camera phone in an easy enough to use package for the average cellphone user.
What issue does a headset solve? Apple at least had heavy competition from Blackberry and Nokia back then. Here they are walking in largely unopposed as there aren't enough customers to bother competing over.
But they lose me every time I hear something about workplace collaboration or gaming.
And maybe it's not a bad product. The Lisa wasn't. It was ludicrously expensive compared to it's competitors though, which sealed its fate regardless of how practical or visionary the computer was.
