There's a bunch of new content on Windows Forms 2.0 available at http://www.windowsforms.net.  The Windows Forms 2.0 section is at http://www.windowsforms.net/Default.aspx?tabindex=5&tabid=60.  There are lots of samples on the new features and controls of Windows Forms 2.0.  There are samples that mimic the look and feel of Outlook, Quicken, File Explorer, Microsoft Money, Internet Explorer, and MSN Messenger (among others).  If you're trying to build professional looking smart client applications, then this is the resource for you!
