I have a slate (705S) and I love it. I have a wireguard server set up on an RPi at home and when I travel I plug in the slate, connect it to the hotel wifi (or Ethernet if I can), and flip the switch to turn on the VPN. All my traffic goes through my home connection, and I can still access my internal services.

I’ve even used it to save the day when an AirB&B’s wifi was too weak for the living room smart tv to connect when the family wanted to watch a movie.
