A:AnswerMy guess is BestBuy is only going to offer it in the midnight color, the apple store is the only place that exclusively offers all the configurations.
A:AnswerThere are only 2 ports and they are both the newer USB type C. Since most thumb drives are USB-A you will need to purchase at least one USB-A to USB-C adapter. Also, know that the MacBooks now use a power cord that ends in a USB-C connector so if your laptop is plugged in you only have one port available.
