Which is better – Virtual Desktop Infrastructure or Presentation Virtualization? If you have, say, a Citrix XenApp PV solution – you may may be tempted at the reduced cost per license of VDI – XenDesktop appears to be almost half the cost per user than XenApp. Maybe you’ve a VMware vSphere back-end and the thought of having one platform to manage is appealing. Maybe you have a different solution – perhaps Quest’s vWorkspace or Ericom’s Webconnect and are wondering what all this fuss about moving between PV and VDI is all about?
