I have taken several trips of 4 weeks or longer - without bringing a computer along. All I had was my phone and everything was just fine. In addition, since I have T-Mobile, I had unlimited data in those other countries, as long as I had bars, I could connect directly to a cell tower. So no problems connecting to a hotel or other wifi network that may not be secure.
I do have a MS Surface at home in addition to a larger desktop and that surface rarely leaves home.
