I totally agree. In the past week I deployed a new VMware cluster with vCenter, and found myself constantly wishing for the desktop client. A lot of the issues I had were related to bugs in the web interface itself, I had to SSH in to fix random things. Apparently, certain 'invalid' VM configurations can cause the web interface to error out completely until the VM is disassociated or edited, even on a brand new cluster. For VM stuff I can use Workstation to administrate them so I was able to change the VM settings from there, but for anything above individual VM control you pretty much need the web UI.
