Keeping my MBPr for as long as possible, in that case.
If they kill the aux jack I'm done buying Mac laptops. I've supported them since before the egg-shaped iMacs, but this is a dealbreaker for me. Wireless audio does not compare to hard-wired.
We need a dongle to listen to music on our headphones and charge the iPhone 7 at the same time.
We need another dongle to charge and use a USB drive on the macbook at the same time.
Now we are going to need another dongle to listen to music on headphones on the macbook pro?
If they do this I'm probably going to get a refurb 15 inch of the previous model or give up on apple altogether.
