Gareth blogged about this video on Dabcc.com. Gareth created an online XenDesktop beta test site when the first beta was released, and has blogged about it numerous times. He likely knows as much or more about the producty than anyone outside of Citrix. Check out his post and his great blog.
I have received a few links to more Tip video, so I will post them later.
There will be numerous XenDesktop technical sessions and live demos at Citrix Synergy. You can click here to register for Citrix Synergy. I will see you in Houston.
