After installing SharePoint 2010 Beta 2 and started playing around with a team site, I tried to create a new list in the site through Site Actions –> More Options… (click on the image for larger image)
I got the create page with a recommendation message to Install Sliverlight for improved creation experience (click on the image for larger image)
After Installing Sliverlight I got this WOW create dialog box which is Sliverlight enabled with a lot of animations and categories for the content.(click on the image for larger image)
This is the Silverlight touch for SharePoint
