I meant to type "And yet if I buy...".
The point is that Apple's argument for going all USB-C on the MBP is that USB-C is the future, and the fact that USB-A is ubiquitous today is not a valid excuse. The MBP team is expecting the entire rest of the world to abandon USB-A and switch to USB-C right now.
But this is undercut by the iPhone team. If Apple truly believed that USB-C was the way to go then the iPhone would have an USB-C connector. It doesn't, because the iPhone team is recognizing that it is premature to abandon a ubiquitous standard.
So if Apple doesn't have the courage of their own convictions, why should the rest of the industry behave any differently?
