I have never bothered looking for MS licencing as it is a ridiculous concept.
I do deploy Novell Licensing which works well and is affordable at te server level. My desktop recommendations are always Ximian or SUSE now, open source with a minimal cost.
If I can deploy 300 SUSE workstations at a cost of less than $100.00 each, including Open Office, what possible reason would anyone have to PAY through the nose for Microsoft's unstable and barely equal offerings?
It just doesn't make economic sense anymroe.
the only drawback in the past was user familiaruty with Windoze. With SUSE and XD2 desktops offerig more for less in an interface that is somewhere between a MAC and a Windoze look, this learnig curve is completely eliminated. I have seen new users (who ONLY know basic MS skills)adapt to SUSE without any effort whatsoever. Seasoned MS users will find it that much easier still.
Again, why would anyoe in thier right mind CHOOSE to pay a LOT more for MS? There simply isn't ANY logic behind it anymore.
