I recently came across a Palm launcher called "AppShelf".
One of the cool things that made me think of GTD was the ability to see both the appointments and tasks within the launcher.
I don't know about you, but I tend to always go back to the launcher when done with an application, and this is where it starts again the next time I fire it up. By doing this I tend to not view my appointments or task list nearly as often as I should.
Anyway, here are a couple of links if you're interested:

Keep in mind that the author of the application is from Japan and english is his second language -- some of the menu items take a little figuring out
