An App Store on Every Mac

The iPhone’s App Store has proven to be such a monumental success that Apple should extend the idea to its other devices and computers such as the Mac and Apple TV.
The main draw for me regarding the App Store is that it is so easy to install apps. It only requires a few clicks to download and install the latest applications. App updates also show up in a centralized interface. Sure, installing an app on Mac OS is already easy, but it can be even easier by having a single click and install process. Having a single App Store service could help developers promote their apps due it’s tight integration with iTunes and also generate more revenue for Apple if they take the standard 30% cut that they usually take with iPhone apps.
A longshot, but something that would be welcome is an App Store on the Apple TV. Boxee already is a fantastic extendable media center platform, but it is not something that the regular user would play with. An App Store for the Apple TV could bring the kind of rich web information that Boxee offers like Weather, Maps, Email, and Stocks in a way that a mainstream consumer could understand. Being able to listen to Pandora via an Apple TV would be an epic win for me personally. There would be a problem with text entry, but I’m sure something could be worked out. The Boxee iPhone app already has demonstrated text entry via the iPhone touchscreen keyboard. A physical keyboard seems out of the question since Steve Jobs has an apparent disdain for buttons.
