Finally I found a good article comparing Ajax with the rest of the equivalent technologies out there. It seems like a good resource to present to the team at Resources. I had mention before that I find web UIs quite rigid and the main alternative I had seen for this in the industry was Flash. However, Flash movies can be big to download, specially if you are on a dial up connection, need the Flash viewver plugin and the skills are rare to obtain. The original article
can be found at the Ajax info site. Enjoy!
