If your organization is looking at deploying VDI (Virtual Desktop Infrastructure), I highly recommend you check out the VDI Smackdown report by PQR. It has a very lengthy and highly detailed feature comparison matrix of leading VDI solutions such as Citrix XenDesktop 4.0 SP1, Microsoft Server 2008 R2 Remote Desktop Services, and VMware View 4.0.1. I’ve never seen such a long comparison table of features between VDI vendors.
There’s no one best solution, as requirements vary widely between organizations and situations. After you think about your VDI use cases, the Smackdown will really help you see how each product stacks up. The full 33 page report is worth reading in its entirity.
