Next generation to do list

I have been doing a lot of research about to do lists lately and I have come across a few that I really like.  The first is Any.Do and another is wunderlist.com.  Both have very nice UX design and are fast and available on multiple platforms.

I recently started working on my own smart to do list/ task list called Livenotes.me.  Check it out and let me know what you think!
