Desktop and Server teams do not play well with each other, it should not be that way but it is.
I did a great business case on VDI (and posted here) but it still got put in limbo. Business cases can be read multiple ways depending on what view you want to see (and that view does not have to be the truth). Also since business cases are for management can you really tell them they are wrong when they want to see things the way they want to?
Longer lifecycle of VDI means less re-purchase of desktop hardware (vendors are not happy) and less work for desktop techs (desktop / helpdesk groups start to panic, seen it already).
Anything with the word "virtual" thinks servers...it's a stigma now.
See number one...
One other key issue, the desktop price keeps on dropping and with VDI server / software and thin client costs prevent the ability to match designs based on capital costs and power savings is a "soft" number in many people's eyes. Better end user management, patching, security, etc...your desktop teams will argue that until the cows come home...
It's a Monday morning and I have not had my Diet Coke so I am still a little cynical...
