Exactly!
The purpose of a docking station is to provide
significant expansion to the device that you wouldn't normally have when not docked. As such, here is my take on the docking station, based on what I've seen and read:
- USB 3.0 Ports -- From all the pics I've seen, the on-device USB 3.0 port is not accessible, so the net result is the same: Just one USB 3.0 port.
- USB 2.0 Ports -- For the docking station, this is an upgrade, as there are none on the SP device.
- Audio -- To reduce the number of devices I have to plug in, I stream my audio from my SP to the external speakers via USB. It's great to have this natively on the docking station, but it definitely is not a game-changer, either.
- Ethernet Port -- I currently have Gigabit Ethernet via USB, so it makes no sense to downgrade to 10/100 on the docking station's Ethernet port.
- DisplayPort -- With the SP2's DP 1.2 support, I am able to daisy-chain my external monitors, so no gain for me here.
So, based on the above, there certainly isn't much of an incentive for me to get the docking station, based on my setup and use case. Hopefully they make a second-generation docking station that addresses what are, to me, shortfalls.
