The "performance" is indeed bad. 256 MB RAM is surely not enough for a J2EE
application like OpenLaszlo and Windows. I have a very good performance
experience with Flex on PowerPC G4 1,2GHz with 1280 MB RAM (development
machine, not yet in production).

That does not have to be a disadvantage. Flash is more cross-browser than AJAX
and AJAX is more cross-platform than Flash. Safari and Konqueror can't render
most of the demos of openrico.org. This cross-browser vs. cross-platform
ratio might change in future because of ongoing efforts to develop an open
source Flash player. The cross-browser DHTML stuff is fragile and I can't see
that it will change in future.

but SWF is not closed, see
http://www.osflash.org and
http://www.oreillynet.com/pub/a/javascript/2002/05/24/swf_not_flash.html.

You can use Flash's accessibility features:
http://www.macromedia.com/macromedia/accessibility/features/flex/overview.htmlAnd you normally don't need crawles accessing your web applications (not web
sites), but you can of course add other interfaces like HTML, WML, SOAP or
XML-RPC to your applications.

Not, it's not yet. Let's see what happens after Adobe has aquired Macromedia.
Maybe Flash/SWF becomes a standard like PDF or PS.
Maybe you find something useful on my list of RIA and RIA related
