OMFG, I am finally getting to dig into SF 2010, and I gotta say I LOVE it! The install routine is perfect, and the features are great. This is a fantastic product from Microsoft. I can't see any reason why everyone isn't running this. Its perfect for hosting applications and allowing for collaboration and document sharing.
I'm going to host an application on it and I am heavily customizing the L&F right now. I will update and maybe add some screen shots when I am done.
