So would you prefer we never transition to USB-C?
Its not about transition, its about crippling a machine that is supposed to be for your work. Just think by yourself, what do pros need? If you are not a professional who takes his own MacBook into clients offices you may not know that you need a handful of adapters since they use all kind of old and new projectors, TVs, monitors, printers, drives and so on. Now if Apple cripples the new MacBook Pro and makes it another Starbucks MacBook I will need to buy more dongles and adapters and hope to never forget or loose one while I am in a clients office. I will need another HDMI dongle, a new SD-Card reader, possibly a USB-C to Headphone adapter, a couple of USB-C to USB-A dongles and a MagSafe adapter. I can't tell my clients they should buy new equipment just because Apple is so courageous to strip all useful things from a pro machine.
