I mention that incase someone gave me a hard time that I needed it to use an external monitor or the fact usb couldnt be use for video output.
The docking station works with the surface 2 or just the pro? I thought it only works on the pro? Seems rather expensive if I can already use my pre-existing hub and monitor to make it a desktop?
Darn it, sorry, for some reason I was thinking about the SP3 the whole time. Probably because it's currently a hot topic here at WPC.
You are right. The docking station is only for the Pro (different versions for the Surface Pro 2 and 3).
If you already have a hub, and you are fine un/plugging the hub and monitor each time, then by all means, do that. It's the cheapest option. If you aren't regularly copying large amounts of data to/from USB 3.0 enabled thumb drives, you aren't missing anything.
The docking station is the route to go if you convert between desktop/mobile modes one or more times a day. It also gets around the bandwidth issues a hub has, but if that doesn't affect you, then who cares.
Good luck!
