Nope! I'm talking about a site I browse to on my PC. If you go here, you can browse the entire market, and when you click "Install" on any app, it automatically installs on your device.

The general idea is that while using an app repository to download a specific app is fine on the phone, it's not the greatest browsing experience. A full desktop or laptop might be better for that.

I think it's also a nice way for people interested in Android to see the apps available.
