I honestly don't buy Apple keeping convenience in mind. For Apple, convenience is not at the top of its priorities. Maybe some people are alienated by the new MBP, but I think most are going to compromise.
The major reason I buy Apple is for the quality, and the way the devices keep working till their last breath. I bought an iPod classic in 2004 that I used until 2011. Seven years of heavy-duty use, much more than I expected. I have an iPad 4 that I bought four years ago, and it's still working great. I'm not even considering to a newer model of the iPad. I dropped my iPhone 6 Plus from a height of about eight feet onto tarmac. It was broken so bad I could see the internal parts, yet it still worked perfectly until I gave it for repair.
I haven't had a MacBook yet, but I have high expectations considering all the other great experiences I've had with Apple.
