Love my iPad for making art with Procreate, reading, playing media, as a universal remote for home automation, games, showing photos to friends, looking up stuff of the internet, reading, for DJing.
There are no messengers, calendars, or communication apps configured on it. So there are no notifications.
I sometimes try it for productivity, but run into limitations quickly. It’s okay for editing a document for a bit, but managing files is already torture.
