I actually find that website almost entirely useless. A to-do list means nothing and demonstrates nothing useful. It has no associations between models and nothing particularly complex. I have tried so many of these frameworks and found crippling flaws in all of them, but on the surface they all look peachy when compared via a to-do app.

It's pretty much only useful if you want to write a to-do app.

I completely disagree. I find it very useful to see small, easy to digest, and easy to compare example apps when new frameworks come out for a first impression to help decide if I want to have a play with it myself.
