Some clients ask us: should I build a native mobile phone app, or should I build a cross-platform browser-based mobile service? 

The choices include iPhone, Android, RIM, Palm, Windows Mobile and Symbian. 

It is estimated that today there are 326,000 Mobile Web sites, compared to 148,000 iPhone apps and 24,000 Android apps. 

Experts forecast that the browser-based mobile web market to grow much faster than the app market.

In February, mobile search company Taptu released a report showing that the future of the Mobile Touch Web is likely to be dominated by cross-platform browser-based mobile web sites - rather than apps built specifically for iPhone, Android, or any other platform.
