What's new with Mobile AJAX?
One interesting effect of Apple's strange stance on third-party iPhone software is that many developers are looking into mobile AJAX again. After all, doesn't have Flash or Java, but it does have a fancy AJAX-capable browser.
Opera's Platform is still considered the primary AJAX platform, but it requires an extended version of the Opera browser and few consumer devices already have the client. Another option is Pocket IE, which supports the XMLHTTP object, but it's hardly cross-platform.
Ever since Open Gardens published an essay on the "disruptive potential" of mobile AJAX in March 2006, mobile AJAX has been constantly "just around the corner," but in the past month or two there have actually been some interesting developments. I wrote that 2007 will see the first round of real mobile AJAX apps. I still think that this is true and my money is still on Opera Platform, but Mojax is definitely worth watching, especially once it hits 1.0. - Eli
