Installer.app was the first "App Store", before Cydia even existed, I wrote it. I spoke to Steve before they launched their App Store -- we were happy to see them open up the platform and provide an official SDK, which was our goal with Installer.app.
I think Apple should either charge considerably less than they do for distribution via their App Stores (that is, even less than 15%) or allow competition. Even more importantly, they need to allow installation of apps via links without requiring an App Store altogether.
They also need to provide wider access to low level APIs (with user confirmation), instead of dumbing it down for developers while keeping all the powerful APIs to themselves.
