First of all, you need to understand that there are several challenges to making mobile commerce a widespread reality. Another involves the issue of cost. Unlike wireline Internet access, when it comes to using smartphones and other wireless devices to access email and the Internet, users pay for each minute they download email and URLs. The content may be authored for each device, or it could be transformed in some way. Authoring becomes expensive as you send data to more devices.
Transformation provides benefits over authoring, namely scalability and flexibility.
But it's not just as easy as removing a few graphics and drastically narrowing the column width, though some are indeed taking this route. Generally, the content and design both need to be optimized for the target device. Other challenges include changing the mindset of developers and IT staff who are literally accustomed to working on the big picture, and selecting from among the increasing number of available solutions. CIOs must be realistic in their expectations when it comes to their ability to fit a mobile commerce solution into a small device. In addition, there are many choices to make about tools between the back-end infrastructure and the mobile device, and it's important to remember that by choosing one solution, it will affect every other choice you make across the entire system.
