What's on your desktop? Now there's an app for that, thanks to the Mac App Store.

The new Mac App Store is launching today it would seem, although one needs to install the new 10.6.6 OSX to get it. Will the new Mac App Store have the same profound effect on our desktop that the existing app store had on mobile apps? Likely not. iPhones, iPod Touches, iPads are mobile devices and usually accompany their users on every outing, not so with laptops and desktops.

With that being said we will likely see a great number of apps from the existing App Store make it into the Mac App Store.

First thoughts around this are positive for me. I like apps that update themselves, as a developer it would also be helpful not having to build up an ecomm system as I suspect in-app purchases will accompany the new SDK for apps in the Mac App Store as well. Of course, Apple will take a healthy chunk of the revenue from the app.

At any rate, apps on iPhones, iPods, iPads will now be ubiquitous across (nearly) all Mac devices.

What do you think? Will this revolutionize the app distribution methodology for desktop apps? Or is this just another cash grab from Apple?
