I bought a USB-C to alighting adapter for my phone, got USB-C Sony wireless headphones, and a couple USB-C adapters for my regular USB 3 devices. Kept all my Thunderbolt peripherals (bought a TB2->3 adapter), and a hub and a video adapter or two (HDMI and Display Port)

$200 later I’m happy but when I use my old 2013 MBP I feel kind of slighted.
