I mentioned Spool on Twitter a few days ago, but the more I use Spool, the more I like it.  I had been using Instapaper for saving things to read later, but I have switched over to Spool.  The big difference is Spool brings all the content off line, including pictures and videos, in to an easy to read/view format.  No internet connection no problem if you are using Spool the content is local on your device.  Watch their video, and sign up for their beta this is a great tool.

Mobile apps are available for iOS and Android, as well as browser plugins to easily save items for later.
