I'd be concerned about getting many users to install/use it, though, because it always takes up a space on the Home screen, when it'll only very rarely get used. I wonder if we'll see more uptake of apps like this when users get on OS 4 with its folders... I could see myself keeping a few folders of "rarely used utility" apps. As it is, I wouldn't keep this app on my device just because of the "clutter" aspect.
The App Store comment saying it should be cheaper made me laugh.
