For several years, I had neither a laptop nor a smart phone, I had a Kindle. And I didn't have Internet at home, so I went to cafes, stores, and the library for internet. Kindles work great.
But there's an addition to this, because I had a black and white Kindle before I got a Kindle Fire, and the old keyboard one had a browser on it ...that worked on cell phone towers for free. I used the internet in black and white! It worked!
This was before Hive, so I didn't use it for that, but I used fb and Twitter with it. 😁
I think they got rid of that feature, though.
