USB-C has somehow made docking stations take a big backwards step. Which is a huge shame because we finally got to a good place with USB3 docking stations, where weird ports on the underside of specific laptops could finally go away in favour of a highly standardized one-cord docking solution.
18 months ago we deployed USB3 docks into a sizeable office space. We were able to standardize on a model that works reliably, every time. The only down-side is the dock can't provide power.
Now we're looking at a similar situation and USB-C is the 'obvious' choice. But it's a far more complicated situation.
Some devices will take a charge, some won't, and you have to match up the power input/output requirements quite carefully. It's a more complex landscape than PoE, for no good reason.
Thunderbolt docks are the only ones we've found to provide reliable operation, but they also suffer from weird docking/un-docking behaviour as well as massive security flaws since you lost a lot of the 'standard' USB safe/abstraction layer stuff by plugging in what is effectively a DMA device.
Yuck, frankly. This shouldn't have been so difficult - Just take USB3, introduce a Power-over-USB capability, and bump the speed. But no.
