You're probably thinking, "there are too many task lists available for the iPhone, and they all do the same thing." You'll get no argument from me there. For me, it's a matter of how well they do it, and Done has the potential to be very fluid to use, taking a little more advantage of the iPhone platform as a user interface. Not having tried it yet, I'm judging by the features listed on the promo page: multiple lists, priorities, colors, shake to sort, as well some more novel innovations. It looks simple ... maybe too simple for some, but potentially ideal for those who shudder at the mention of GTD (sorry, did I say that too loudly?).
One novel feature which I don't believe exists in other task managers, yet, is a snapshot capability which will replace your iPhone/iPod touch wallpaper with an image showing your top 6 tasks. The app was recently submitted to the App Store, and is awaiting approval. That's where you -- with your highly-developed sense of humor and savage wit -- come into play.
Chilli X would like to have clever task lists in the promo shots for the app. They are -- by their own admission -- developers and not comedians. You can see their prior attempts at their website, but -- and I say this with love -- they're not great. If you think you have the comedic chops to write a truly fun, interesting and humorous list, leave a submission here in the comments. Chilli X will be watching and picking their favorite entries, the authors of which will receive free copies of Done, in addition to the glory of having their carefully-crafted task sequences displayed in the screenshots of the app in the App Store.
I've heard rumors indicating that App Store glory is often accompanied by prolonged health benefits and above average success with dating prospects, but your results may vary (the TUAW legal department kindly asks me to inform you that TUAW makes no such promises, and takes no responsibility for this post).
Chilli X does offer one stipulation: "keep them clean(ish) and don't say nasty things about anybody." Easy enough.
