Apple has finally launched the App Store for Mac. It works just like the iOS version, with users being able to download applications from iTunes. If you buy or download a free app, it will immediately jump to the dock with an iOS-esque progress bar. Once the download completes, you can launch the app. Mac users can download the necessary updates right now. Strangely though, there seems to be lots of people trying to get them at the moment so you might want to take your time.
