I don't know if it's my favorite but I use it too: the smartphone. It is a small device that allows us to communicate and find information we need in the web. It is really like a mini computer because you can do everything with it. I didn't have one until I turned 16, and it was a small cell that my sister was not going to use anymore because she had bought a better one. Then I got a better one, more modern, so the first one I use to listen to music only. I use my new smartphone every day and to do almost everything: communicate with others, find information, send emails, read, see memes, watch series, play videogames, among other. In simples words, I use it to comunicate and entertain. And I like it because it facilitates me daily works and I can take it everywhere. If it didn't exist I suppose I would use the computer to replace their tasks, but everything would be slower and more complicated.
