I use Instapaper, and switched from Pocket way back when for these exact reasons (highlights and saving my position). They're implemented wonderfully.

This sounds promising.

Pocket's inability to remember the current article/position is one of the most obvious, annoying, and (at least by me) reported bugs ever. It makes the app close to useless. Yet they're unwilling to do anything about it. So I'll happily switch for this alone. And highlights/notes is a dream comes true

Going to give Instapaper a shot. Thanks!
