I was planning on buying one for $39 prior to Christmas. I just couldn't come up with enough things to make it do to make it worth my time. Buying pizza from one vendor, or getting an Uber driver to the house isn't anything I would ever do.
Everything else it does I can already do fairly easily with current technology at hand. The reason I asked what you did with it in your RV was not to make it RV related, but to see exactly what you did with it that made it so useful. Maybe I'm overlooking something.
