Rear:
3x USB 2.0
1x 10/100 Mbit LAN
1x Mini DisplayPort
2x Jack
1x Power
The USB ports are placed far enough apart that even larger USB sticks / dongles easily tuned fit, well resolved. I would have still one or the other connection with USB 2.0 or 3.0 required, which could be targeted but I can not answer.
The power supply looks like the 48W-surface power supply, just missing the USB port and the DC plug is also another.
Service:
Touch / Type Cover agree, Surface Pro reinstellen, push together the dock baking and ready.
(Update 10.2 -. The Touch / Type Cover can be tuned and also use during docking.)
Conclusion: Who 100Mbit sufficient and has a USB hub, it is the perfect solution for Dock Pro. I therefore forgive 4.6 stars rounded up. 5
