This may sound snarky but we've run the 7370 version of their lineup and chosen to abandon them for T460s at the time being. There are some pretty not cool things going on with the thunderbolt subsystem when it comes to displays and network cards.

Edit: to go into a bit more detail, we seem to see arbitrary packet loss on the thunderbolt based network cards (pigtails and docking stations), as well as sometimes the MAC changes, which messes with our radius system.

Furthermore, there are some issues with hardware acceleration on skylake so having a QHD screen is basically a waste if you want to try and view any QHD video content.

We ran Arch the entire time my team was on these and we kept the wiki up for this product. It just seemed that we were fighting a loosing battle with Dell's docks and with Intel's skylake stuff.
