So Finally I was able to do my session about introduction to new Features in SharePoint Designer 2010 last week at SharePoint Saturday Arabia. Becuase I only had 50 minutes i made the pace really fast and went on th demo almost everything other than developing workflows. I got nice feedback from people on twitter. the video of the session will be available very soon and the slides are available below.
I will upload the video once I receive the link from End User SharePoint guys. Thanks to them for giving me the oppertunity.
