Long story short, for web browsing you can use your favorite browser, what ever it is. Well, that’s a start, for video playing is there VLC. Office support is done by LibreOffice, it makes M$ compatible documents. Graphics editor is there called Gimp and 3D modelling app Blender. Games, yes there are some, but better yet get a console like a PlayStation. Linux maybe starts slower but it’s faster ready, so that’s that.
