Rich Client Technologies

Still trying to find my way into the Rich client technologies, I just read those articles (in french):

• Quel client riche Java sur le poste de l’utilisateur?
• Client riche: l’inévitable fusion des architectures client-serveur et web

So fo me the main concurrent are:

• Linux Desktop
• SuSE Desktop
• Desktop System (JDS)
• xalm (Longhorn)
• WCTRE
• XUL de Mozilla
• Flex de Macromedia
• Acrobat Reader
• Java:
• SwiXML,
• Thinlet,
• SwingML,
• JellySwing,
• AUIML,
• xmlgui,
• Speed GJ,
• xWidglets,
• Ultrid,
• Altio
• Jndc

Now wich one do you choose ?! (take a bet...)
