I just ordered the Samsung T3 1TB drive for my incoming MBP (aka tbMBP, tbrMBP, etc). I also grabbed a little usb-c "hub" that has a SD, microSD, and a few USB-A ports on it. Just wondering what others are grabbing. Aside from the SD card, I really don't see many other cables/dongles I'm going to need as I can see adopting usb-c pretty quickly.
