I don't get it. Realistically there is almost nothing available that can make use of TB3. I don't see the point of these ports right now. Reminds me of the firewire ports of days gone by. I have TB3 on my XPS 15 but don't use it in general since I have no peripherals that can use it. I did however buy a TB3 disk enclosure and put a 950SSD into it to see if the hype was real. In reality since I share my disks between the XPS and SP4 I find USB more convenient and in real world scenarios haven't noticed a difference in performance. I just don't see the point of TB3 yet. Maybe if more peripherals were available it could make sense. But right now I don't understand why everyone is bemoaning the missing TB3 that you cant really use.
