I've made a Firefox add-on to let you quickly save a page as a task.

https://addons.mozilla.org/en-US/firefox/addon/moo-later/

I created this as I quite often want to save a page to read later and nothing else was doing what I wanted. I intend to add some more features but it's not going to be a full client, just for quickly creating tasks. Comments welcome, the code is open source on GitHub if your interested.
