Dead on Arrival for our company. We only buy Thunderbolt 3 equipped notebooks for compatibility with our Dockingstation-Flexdesk setups.

I would have bought them in a heartbeat over Dell XPS 13s for our Customer Support guys.

It makes me really sad because this points to longer clinging to the Surface Pro 3 Connector, so the next Surface Pro & Surface Book are likely not to ditch it in favor of TB3. I'm still on my Surface Pro 2 and want to upgrade badly, but this makes me look elsewhere. Sadly.
