Which clients are those? Outlook 2010 seems to handle it fine?
Doesn't Forefront also require you have a Windows Server 2003 or later with Forefront Endpoint Protection 2010 server and System Center Configuration Manager 2007? That'd end up being $$$$
We are running ForeFront (not sure of the version), and we don't require SCOM or anything else - just (as you mentioned) Windows Server 2003 or later in addition to the ForeFront licensing.
I have to note, we only really use it as we are MS Partners and as such get it for free...
To be honest one of the big attractions Dell has for me is their service and warranties. If anything on notebook or PC dies, you call their support line and then the next day you have a replacement part in your hands. Especially in your case, where you have hundreds of machines. Hardware failures on whiteboxes where you have to swop out the component, interface with the differernt suppliers, and sometimes wait up to a week for a replacement is going to eat up a LOT of your time. Eventually, I would speculate, the amount of extra time you spend on hardware support would be much, much more (in $) terms than what you saved by building cheaper PCs.
I actually find this to be a rather short sighed and arrogant comment.
With the amount of updates coming through these days its quite probably impractical for each person or organization to test them all. If you were to do that you would probably be testing patches all the time - and I assure you that in smaller organization this has a cost impact that is extremely difficult to justify.
Worse, imagine you didn't deploy a security update as soon as possible and you get hit by a malware attack - not fun.
