There's just no escaping the app model. Apple today announced that it will open a special App Store just for Mac computers on Jan. 6.

Here's the statement from CEO Steve Jobs:

"The App Store revolutionized mobile apps. We hope to do the same for PC apps with the Mac App Store by making finding and buying PC apps easy and fun. We can't wait to get started on Jan 6."

This is just the latest expansion of the model that began on mobile phones with the App Store for the iPhone. It has since found its way into TVs, online social networks and even some emerging activity in automobiles. Integrating into the computer is just a natural step, as indicated by Google's new store for the Chrome browser and operating system.

It's not yet clear how closely the Mac app store will mirror Apple's mobile version. There are outstanding questions as to whether Mac apps will allow in-app purchases and whether the "There's an App for That" ad campaign will include Mac apps as well.

And despite the fact that Mac apps won't take advantage of the innovative capbilities of the iPod/iPad apps (touchscreen, mobilility, etc.), overall it does add yet another platform for app developers to distribute their efforts.
