Apple loves to kill its own products. Cal hears voices:
How will Apple Glasses differ?
Screen real estate. Once you’ve used a Retina 5K iMac then anything else is, well, less. How about an iPhone-like display on your face in the form of a pair of glasses; initially tethered to your iPhone of course, but over time much like Watch.
If Apple Glasses can do all Watch can do and probably more, then do you need both? Will Glasses that mimic and improve upon what Watch does now be an appropriate and public representation of the iPhone?
I’d still buy both.
