“Serious” computing would be using several applications that chain together to create an end product.

Case in point: authoring academic papers. If you have a local or self-hosted Zotero collection, you will want to cite them. Any desktop platform allows you to use [word processor of choice] and Zotero together fairly seamlessly.

This is a big kludge on iPadOS where you keep switching back and forth between Pages/Word and Zotero to paste in a citation key, which then makes it untenable long-term because the attention break is too great.
