The article talks about installing apps to your phone while you are browsing the web and reading about them on a different device. You still have to fire up the App Store on your iPhone and find the app and download it (or use iTunes to transfer it) if you bought it using the iPad. On Android, it's installed on your phone automatically without having to visit the Market app to find it.

Ah, thanks. But do installing application from Amazon App Store works that way too?

Currently not, but nothing prevents Amazon from implementing it. It is actually very simple, when the user clicks on Install button on the Android Market web, it then sends c2dm [1] message to your device and the localy installed Android Market app pulls the installation file.

Amazon is free to do the same thing.

One small clarification - Amazon is free to do part of the process (download it automatically), but Amazon cannot install the application automatically on most phones. The actual installation step requires privileges that the Amazon Market app doesn't have access to (but the Android Market app does).

Of course, custom Amazon Android devices won't have that restriction.
