= open source software for Rich Internet Applications
"OpenLaszlo is often talked about as an open source competitor to Adobe's Flex, because both are rich client application development platforms. And from the user's perspective, a website built with Laszlo is almost identical to a website built with Flash (indeed OpenLaszlo has a Flash run-time option).
All in all, OpenLaszlo is a compelling platform for building rich Ajax applications - or even Flash apps. They have a hard road to hoe competing against Adobe, a comparatively huge company with many more resources at their disposal (internal developers, marketing, brand name, money, etc). But being open source gives OpenLaszlo a lot of credibility in the developer community. It would be even better if they got a couple more 'glamor' projects like the Pandora one, to raise their profile in the consumer world."
