Mobile apps? It's still a growing market and now Apple is also releasing the app store for its other lines.
Bruce Elgort recently posted an entry (http://www.bruceelgort.com/blogs/be.nsf/plinks/BELT-8AF2BV) on how we stumbled upon this for a local business and now he's receiving additional requests. You could always offer local businesses the option to develop applications for iPhones, Blackberries and Android devices. One thing for sure is that this market is not as saturated as others.
