The media these days are full of stories of people making huge sums of money through a relatively short period of time when you create applications for the iPhone, be it a simple application to play sounds from "Star Wars" or the more advanced and useful applications that increase efficiency and t. e. development of applications for the iPhone and IPod Touch is seen by many as one of the few booming sectors in a dark world economy.

My understanding of the business model now in the iTunes Store application is that you only pay for the application once, and updated applications are not treated as new applications that do not pay. For users who are a pleasure to hear, as in the early stages of development of applications for this platform new media are often errors in the first release from any application, and better, as developers take advantage of Apple development platform, applications will continue to grow and get more advanced .

But the question that was asked, how long until the iPhone becomes aware that some of the industry to make your business more sustainable, constant innovation is insufficient, and to find ways to earn more money from applications have already been created and put on the market.

Once the iPhone / IPod Touch application industry is beginning a more mature, which could take years, increased competition and the user will be more important for applications that will download amongh 20000 + applications already available in the iTunes Store App. Applications for the quality you are always improving and growing, the next step would be to charge for major updates, possibly in a different price level after the initial boot.

This is the way that other industries take advantage of cash cows in its product portfolio, because the rules for management of the business portfolio and will not change just because a new industry might have arisen.

Personally, I would not be a problem with paying a few major upgrade for the application you already have and which I consider worthy of improvement, but I hope that I would have even the option to check for updates before deciding to buy, as you can so Many software for Mac or PC.

With regard to the applications Apple iTunes Store, and will no longer have money to have people to pay for the modernization of applications, but have to wonder why the developers of applications that must share the value of any improvements to Apple. Perhaps, instead, we see the functionality that can upgrade some applications directly within the applications, and software, which is the developer of applications will be my preference.
