This would be great, though in todays interconnected world, it's hardly enough (for me anyway).
I've been through dozens of "todo apps", and most are either too simple or too complex, or doesn't support a sync i can use, or not available on "all" platforms, so ultimately i've settled on Org-mode backed by cloud storage for "sync".
It (for me) provides a simple enough interface that i can quickly add simple tasks, but also allows me to create more complex ones. It also has clients on just about every platform i use, including mobile.
