I feel like people love bashing apple when they make major changes to their hardware in a direction that might not be the current expectation. When has Apple not gone out on a limb to challenge current standards? When it comes to owning a computer, I expect that at purchase it will last me 4-6 years. Is a little in convenience for the first maybe 6 months to a year worth it? Yes, because then the rest of its life everyone else is doing the same exact things. Changing to USB-C external accessories is the same exact process when Apple switched from 30pin to lightning. Everyone said Apple is the dumbest company for making people re buy all new accessories or buy converters. How can you expect any technology company to move forward with that type of attitude? Are we suppose to stay in our boxes because we don't want to be inconvenienced when in a years time we're not going to think anything of it. Was everyone inconvenienced when people bought DVD players at $1000 a piece to try and convert massive libraries to disc? People have had 4K televisions for years when there simply has not been any content til recently. Price people pay for being early adopters.
Someone happy with mediocrity. Just because Apple chooses to "challenge current standards" doesn't make it good or right or what everybody wants. Apple banks on people like you who will just blindly shell out their cash for whatever Apple puts out. Fortunately, there are plenty of people who will call Apple out for making poor decisions.
Enjoy all those USB-C ports. Get a big bag to hold all those adapters and dongles.
