I've had the new Macbook for a couple of weeks now and I must say i have had no issues whatsoever with the one port scenario. I use this as my secondary portable computer and use with lightroom, photo mechanic, mail, safari etc. Airdrop has proven to be much faster than copying to a thumbdrive so as it stands I haven't needed another port. I think 2 usb-c ports would be ideal, but no issues having just one so far.
