InfoWorld’s Peter Wayner surveys the development landscape for six smartphone platforms. The survey — which includes the iPhone, Android, BlackBerry, Windows Mobile, Symbian, and Palm — shows how wide open the mobile development field has become. ‘Unlike the desktop world, there are more than a few players, and the niches are evolving, merging, and splitting,’ Wayner writes. ‘Some of the platforms are better for tightly integrated enterprises, while others offer much better opportunities for gamers and experimenters. Some require the highest-end hardware with the most expensive contracts, while others work well with cheap phones too.’ Throughout the survey, Wayner offers insights and questions to help you target the right device, as well as extensive tips for pursuing the cross-platform option: Web apps for smartphones.
