It isn't available on mobile AFAIK, which is like my primary use for pocket etc., saving links to later read on my laptop

I do use it, on Desktop only. On mobile I still use Pocket only. Actually I use an Obsidian plugin to sync my Pocket saves into Obsidian. That plugin might be a great backup/way-out strategy for Pocket users.

I use it pretty extensively. Aside from being a pretty poor experience on mobile (it straight up can't be used on iOS at all, works ok on Android), it's the best web clipper I've used.

I really wish they would integrate the functionality into Obsidian itself, though I think there are technical limitations with it.

I haven't tried it, but I have used Notion Web Clipper. It works, but the experience is nowhere near the same.
