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.
