In addition, continuing to drive market adoption of desktop virtualization, the company unveiled a new segment of the Citrix Ready Program – Desktop Appliances for Citrix XenDesktop™. This new partner initiative is aimed at establishing standards for a new class of device purpose-built to deliver a superior user experience when combined with XenDesktop.

Attendees get the benefit of four events with one registration: a traditional user conference with the latest on Citrix products; an application delivery expo of breakout tracks, products and solutions; an IT 2.0 business symposium exclusively for C-level professionals; and Geek Speak Live, an un-conference where tech geeks, analysts and bloggers pick the topics and facilitate the sessions. Citrix Synergy will be at the George R. Brown Convention Center in Houston, from May 20 to May 23, 2008. More information is available at http://www.citrixsynergy.com.
