I've been using static copies of Wikipedia for years; they're great to have when traveling. I mostly use the Kiwix app. Their ZIM format database for all English is 83 GB; 43 GB for one without pictures. Compares nicely to the 43 GB here.
I once spent an hour in the Louvre learning about Rubens astonishing paintings of Marie de' Medici thanks to Kiwix. Without it I was just like "huh, nice paintings, I wonder what they are?" They're incredible and I owe that moment of kismet to Wikipedia, Kiwix, and my mobile phone. https://en.wikipedia.org/wiki/Marie_de%27_Medici_cycle
