Isn't it fun when user experience was supposed to be better?

Yeap. User experience is the main drive for AJAX applications. But what to do when user experience sucks because of AJAX?

That will often happen with low bandwidth. I've been experiencing this connecting via GPRS.

One of the worse AJAX experience you can get is with hotmail.com - but at least they give you the opportunity to use the non AJAX version.

Google Analytics is a nightmare - from far the worst experience over slow connection. No surprise here, being one of the best user experiences over normal bandwidth.

Google mail is decent over slow connections, which may come as no surprise, given that gmail offers a plain and simple user experience.

Blogger.com experience is also decent, and above all very tolerant to intermittent connectivity. This is one of the few applications that asserts lack of connectivity - the majority just fail silently...
