Pocket also syncs across devices, which is something I use frequently - I save something on my desktop then read it on my iPad. This still requires you to take the action of hitting 'Now', so could easily turn into a black hole.
Why do I say this is better than Pocket? Pocket's like a black hole where you throw lots of articles into...but then never go back and look at them again. However, for this extension, you can save articles. And then when you have free time, you hit Now and it'll bring back your last saved article!
