AJAX is changing that, but at the cost of increasing the weight of
the pages (i.e., all that JavaScript means loading the page takes
longer). This is no problem for Intranet apps, but lots of people
are still on dialup.

Not to be pedantic, but AJAX is a technology using JavaScript and XML which
still needs to be passed from the server to the client. An intelligent
programmer uses a bunch of scripts to talk back and forth between the server
and client to make it appear that the web-page is more responsive. It's
mostly smoke and mirrors though. A scripting language, being uncompiled is
never as fast as a compiled language. and 33 Kbit dialup or an 8 Mbit cable
or even a T3 connection is still not as fast as a 100 Mbit LAN, not to
mention a gigabit LAN. The AJAX approach is somewhat similar to a Terminal
Server in that once the page image is loaded, only little bits of data are
passed back and forth. Lastly, being a web technology without a fantastic
IDE and built-in database functionality, it will never be as fast to develop
in as is Access.

To be fair, there are some things in AJAX's favor. For 1, it is
cross-platform. Secondly, it leverages mostly existing technologies.

For less than 50 users on a LAN (and sometimes more) and reasonable amounts
of data (say 1/2 GB) I don't think that there's much that can approach
Access in speed of development, rollout, and functionality, or at anywhere
near the cost. As long as there is a reasonable number of users (20 to 30) a
Terminal Server is just fine, and far less expensive than a comparable web
application.
