I recently wrote a report for University on mobile development. The question I posed was;
"Will mobile application development continue to be lucrative in a market with increasing emphasis on cloud and web based services?".
I have been working a great deal with mobile technologies and I feel I have gained some insight into the direction is which the industry is heading.

The site uses jQuery Mobile to render the pages. This is an amazing tool, though still in Beta. I converted it into an Android Application using PhoneGap. Information about both these technologies can be found within the report.
