I like that Xendesktop was able to incorporate with VMware very well. We were able to build our environment of VMs and easily get them imported into the desktop controllers and have them populate.
We were also able to allow our helpdesk staff to use a web based version of the console to help troubleshooting prior to hitting higher level engineers. The web console contained a wealth of knowledge that could be passed up the chain and not requiring engineers to track those down.
The management console was very robust and easily laid out. Configuring desktop groups and catalogs was easy and very straight forward.
my FAVORITE part is that the console outputs all of the actions into powershell, which makes it very easy to script able Xendesktop.
I disliked that the UI was somewhat clunky. Also the Xendesktop 7 was kind of a drastic change from the Xendesktop 5.5 environment.
It is a rock solid platform for any VDI environment and incorporates with VMware vms.
We were implementing a solution where we could manage all VMs from a single location and a single piece of software. This allowed our engineers to pinpoint the errors and our help desk to help relay better information up to the engineers.
