I chose 'Apps Beyond Mobile' because I'm interested in the idea of having the same app options for mobile devices for computers. While the Mozilla Firefox-based apps doesn't have much to offer, the Mac App Store has most, if not all, of the apps you can find on the iPhone or iTouch. The only downfall of the Mac App Store is that its only available for Mac users.
I think this trend will be popular in 2011 because its something that Mac users can utilize without having to need an iPhone or iTouch. The Mozilla Firefox apps could always expand their app store which would be excellent for Windows users to have. The app area is growing more popular with each new app, and these catalogs for apps are just the thing to get them out to the public in 2011.
