I can only hope Apple takes this serious.
A notebook with only one USB-Port needs to have bluetooth, so some external devices (mouse, keyboard, audio) can be connected. I'm running Windows 8.1 Pro (x64) on the new MacBook Retina, 12-inch. I can't install Win 7, I can't install Win 10 beta and I'm stuck with that USB-C port and Win 8.1, without bluetooth. I'm very upset about my decision to invest in Apple technology. Dell XPS 13 probably would have been a far better choice.
