Recently, I read an article in PC World entitled "Why the Number of Apps in the App Store Doesn't Matter".  You can read the article here.  I couldn't disagree more. 

This article is heavily based on the thought that everyone who uses a smart phone is an average citizen and not technology savvy.  Of course, not all of us are geniuses when it comes to computers, but having a good number of apps to choose from in certain key areas is crucial to a good mobile platform and a happier user base.  Yes, the standard web brand apps like Facebook, Pandora, and Angry Birds, will be downloaded the most, but in other more competitive markets, like CRM, Invoicing, Practice Management, Games, Photo Enhancements, etc., there are a host of companies vying to get your app dollar, and the more the merrier.  This way the user is more apt to find an application that fits the entire needs of his or her particular usage.  As more small businesses embrace the cloud SaaS movement, the platform which is easiest to program for will win, and will enjoy having more apps, more satisfied customers, and more revenue.  Just take a look at Apple's success with the app store and tell me that the number of apps does not matter.  Also, let me give a comparison to a similar segment which relies heavily on a multitude of software providers to be successful.  The gaming console, sure everyone has a copy of Halo3, but if the XBOX only had a few Microsoft titles and little to no support from outside influences, it would not have been successful.  I think the same principle in the long run will apply here.
