Nobody is FORCING anyone to upgrade.
If what you have is workig, why change it? Just because it's new?
I have some systems on Win2KPro, some on Win2kServer and some on XP-Pro. 1 is on Win2k3, but unless I have specific hardware, drive rof components support need, I don't and won't be upgrading
That way, by the time I do decide to move up, the required hardware is cheap
