Laszlo is about XML, not about Flash

I know I have talked already about Laszlo, but I should say this article caught me. “Laszlo is XML technology, not Flash technology” by David Temkin that explains how the Laszlo XUL server toolkit differs from Macromedia’s XUL server offering (aka Flex/MXML).

David asks which one is your choice?
Macromedia’s MXML which is tightly bound only to the Flash player and authoring tool?.
Microsoft’s upcoming XAML, which is tightly bound to Microsoft’s Avalon/WinFX client framework?
Or Laszlo’s XML language and framework which is self-contained (no need to use ActionScript APIs, Flash MX, C#, “code behind,” or any other external language) and designed expressly for development of rich interactivity to deliver this application into Macromedia (Flash), Microsoft (Longhorn/Avalon), and Java/J2ME runtimes or anyother powerful client that may arise in future.

David is the CTO of Laszlo Systems so don’t expect a fair and balanced story. Full story here.

What’s your take on it? Do server-side XUL toolkits have a future?
