Yeah it’s good for primary schools and dyslexic folk. And comics.
Also, if you use white text on a blue background it’s even clearer – you can set Word to display like this is you have really bad dyslexia/want to piss someone off who doesn’t know how to change it back.
Although I’m sure there was a recent study that found Arial’s even clearer than Comic Sans, and that doesn’t look like it’s for children.
