Are app stores stunting the growth of browser-based apps?

The AppStore model is not impeding development of web-based apps for mobile devices. Rather, it's generating a flurry of mobile app development, showing consumers and business users that mobile devices are capable of more than we ever imagined!

There are valid reasons for differing approaches to app development, usually driven by the app itself, performance, or user experience. Whichever approach is taken, the AppStore is a great way to promote and sell.

App Stores aren't stunning the growth of Web applications. Both have limitations requiring a solution before the Mobilizing of for example the Enterprise will really take off.
In the case of Native Mobile Apps I believe the five (5) most important challenges to be:
1.preventing wildfire development of unofficial mobile enterprise applications;
2.ensuring the integration of in-house and outsourced developed applications;
3.managing of a growing multitude of mobile devices;
4.managing of an equally growing multitude of mobile applications; and
5.securing of (corporate) data both over the public network and in case of loss or theft of the mobile phones;

Web Applications on the other side of the spectrum represent a different set of challenges. Most of these are caused by the limitations of the Web browser. The four (4) most important challenges are about NOT being able to :

1.integrate with the Mobile phones native User Interface;
2.interactively push generic (all) data instead of polling data;
3.horizontally communicate with other applications and databases; and
4.control the mobile phone’s hardware and OS capabilities (audio/video, GPS etc.)

Solving the above challenges will result in a exponential growth of Mobile Services
