Tomorrow is the last day of the AJAX World conference here in NYC. Aside from running into my old friend Fuaat, it has been a remarkable few days. It is very exciting to see the rapid progress of the client-side browser toolkits in the form of the AJAX frameworks coming to fruition. Ironic though at the same time that these technologies seem like throw backs to the earliest days of developing on Windows – little documentation, no IDE, and very basic debugging. In short, there’s no doubt where its headed, but the developers will be tearing their hair out to get there.
 Its exciting to see the promise of AJAX on mobile devices and how these applications hold the promise of being able to have common code across platforms and devices. Clearly, applications must be developed for an audience – and mobile audiences often want something different. Still, I can’t help but to think, even my very capable WM5 device with IE lacks an appreciable support for Javascript. There seems to be no real relief in the near term to give us ubiquitous mobile development. J2ME still comes the closest today. I’ve been spending considerable time thinking about the mobile space lately. It seems clear that the number of devices coupled with the evolution of data services and lack of the “killer app” provides a greenfield of opportunity.
