I had the same pleasant surprise browsing through STL files for 3d printing; it's nice to be able to view them right in the finder.

Preview is one of macOS' best features, IMO. It's so simple and ubiquitous, but it can open practically anything and does a great job of it. Reading a PDF in it is buttery-smooth, you can even do a respectable amount of editing - both PDFs and images - directly within it. It's one of the last great examples of Just Works.

So true! Preview is one of those apps that Just Works™. I recently opened a PDF on a Windows 10 computer and was slightly shocked that a _web browser_ opened up to present the PDF. Being able to easily and quickly annotate a screen shots and photos for documentation is a huge boon, too.

Not to forget how easy it is to edit and annotate the screenshots using Preview in macOS.
