Both TVs I tried in the house offered easy access to an HDMI port and USB (for power). Setting up wifi was also relatively easy. No training was required for the families who joined us (the concept of a remote is pretty universal) and for those wanting to use their own Netflix or YouTube accounts, they were able to "cast" from their device to the FireTV stick.
I think in terms of providing the familiarity and convenience of home entertainment while traveling (in the US), this is now a complete and effective solution.
