The first use-case that came to mind for me is research. A distraction-free dedicated application for wikipedia could be a great way to keep organized, especially if new features are added and expanded upon over time that go beyond the typical browser experience.
It’s not a workflow for everyone and if wikipedia is something that’s usually just accessed through other search engines then this probably won’t be all that useful to you.
Same here! Still carry mine around and it’s partitioned so it’s also useful when someone wants to share a large file but doesn’t have the time to upload it or have the cloud storage to host it
