I enjoy Pinner for iOS - http://pinnerapp.net/.

I very happily second that recommendation. For OS X, Spillo is quite wonderful.

I also recommend both those apps. I use them daily.

It might be helpful for you to have a look through there and see if any of them have a stand out 'read it later' experience.

I use PinDroid on Android. I mostly bookmark things on mobile to read on a bigger screen though, so I can't comment on how it works the other direction.
