Yeah, I've got one too. (And before it a larger, slower but still USB-powered ASUS.) Good for tons of things. Configuration and/or changes can be a bitch, but once setup right it's quite versatile.
Specifically regarding travel, I'm looking forward to an Amazon Fire TV stick update for web browser to login into guest hotel networks. Everything else I usually wirelessly tether to my phone (where I have solid LTE coverage).
