Quick question for the webheads in the audience

Is there any reason for WPF/E to exist?

I’ve spent a bit of time trying to decipher their marketspeak to find out if there’s anything there besides a reinvention of SVG with added limitations on development and server platform... which is to say, I can totally see why Microsoft would like people to use it. What I can’t figure out is whether there’s value in it for anyone who isn’t Microsoft.

Can anyone who’s played with this already save me some research hours?
