Yes. But she was comparing rapid app dev kits, not programming languages;
Delphi and VB are fast GUI-builders.

Yes. But if you're going to do that, why bother with client-side
programming? I suppose if your app needs advantages 1 & 2, I guess ...

And applying app changes across sessions on a terminal server is still
significantly more trouble than applying a change to a web app. With a PHP
app, you just save the new file in /wwwroot, and bang! It's applied to all
users.

If you want home access to a client side app, you have to mess with VPNs and
firewalls and/or remote terminal services. Ever try providing support for
150 user with gods know what running on their home machines, along with more
viruses than megabytes of ram? (we had a fun conversation when the IT dept
at one client got a phone call from a staff member who couldn't figure out
how to install Mozilla. Turns out the staffer had an Amiga)

For a web app, you just route a path from the web server to the internet.
Then tell the user to use a brower. Very easy.

From my perspective, the age of the "thin client" is here.
