I think it is very common nowdays ajax applications ,since the big number of companies that build Strong Ajax applications , but the issue is that Ajax Applications doesn't perform always good in most browsers even there is a some adavnaced javascript libararies(-prototypejs-jquery-yahoo libarary...) for managing the cross-browser compatibility.

as Ryan Stewart in ZDnet

Ajax is a simple and elegant tool, which is why it’s so powerful. There are a ton of good Ajax applications out there, and as a technology, it deserves all of the attention that it gets. However when developing any kind of application, you need to use the best tool for the job. In this case, Ajax falls far short of technologies like Flex, WPF, and OpenLaszlo. Now, I realize that only one of those products is out for commercial release, but companies looking to build rich, high-experience applications shouldn’t be using Ajax, they should be looking at the next generation of RIAs.

I think that Rich Internet Apps, although very powerful (as Ryan says), simply do not have the flexibility and sheer uptake to seriously challenge Ajax as a Web development platform. This may change in the future, especially if Microsoft has something to say about it. Also companies like Macromedia continue to push the RIA vision. I think that’s great and I expect a lot of innovation when it comes to Web/desktop integration. But it’s not time to write off Ajax just yet.
