I have just been having a good look at a new GTD application to hit the scene. It is called Things, and comes from CulturedCode.com.
I have not yet had chance to play with it although I have signed up to their newsletter so hopefully I will get on the Alpha/Beta program to test it out.
Must admit that it does "look" nice. I am still Alpha testing OmniFocus and I have migrated most of my projects and next actions away from iGTD to OmniFocus now. Must admit that I am loving OmniFocus. They just seem to have thought of so many keystroke saving usability functions that it makes using it a dream. I must admit that Things seems to "look" nicer than OmniFocus, but when I review them both I will report back on the findings.
