In terms of the tools, honestly they were mostly working better than the RTM of VS 2003. I'm already sold there. As a Web jockey, having an HTML editor that won't f-up my code is a nice change after years of the super-nasty 2003 version.
In terms of the framework itself, I don't have anything that I think I'm ready to put "out there," but when I do, I'm basically looking for the ability to perofrm under load for days, not break, and pass tests. I'm not that demanding. Or am I? :)
