Depends on your use-cases, I for example can't wait to get decent speed external disk space, something that only thunderbolt 3 in usb-c on the new macs delivers. Why? Travel and video editing for example. Backups. Virtual machines. The new wave of SSD's are too fast for any existing peripheral bus.
