Which IMHO is the reason why no software for personal managment of stuff will ever be good enough. We all want the perfect tailor-made suit to work with, but we don't wanna go to the tailor and pay for it. And even worst, we grow, we change, so custom-made solution today might not do it tomorrow.

I think for that reason applications with a programatic approach are the real solution for organization like notes or tasks. Something scriptable is a good start for this.
