There is not a Windows OS that is as stable as a good UNIX distro. Sorry, but that will never happen. UNIX has way to many years of development under its belt and it continues and will continue.
As far as in the MS family of OS"s, I agree W2K is the most stable for many things server related.
You and I have different perspectives on things related to computer advancement Mini, and we have discussed them ad nauseum, so I will not go there.
As far as ease of use goes, it all depends on your experience and knowledge. I find MS OS's to be a pain in the butt to setup and configure for many things.
A good UNIX is easy to setup and configure for me. My little box at home took me about two hours to install and setup. It's running all the router chores, firewall, SMTP, POP3, Apache, PHP, MySQL, bulletin board and has been up for almost two years now.
I challenge the most knowledgable Windows expert to get all the above up and running from in that time, including the OS installation. Even if you do, it will need a periodic rebooting.
Oh, and my little server is a 600Mhz P3, with 128MB of ram.
I am all for advancements, but the path we are headed down is a dangerous one as far as I am concerned. I see the day when we turn on our computer and it tells us we have used up our allotted time and it will be busy being used by someone else, so go mow the yard. MS would poop themselves if they could make it happen sooner than later.
Ignorance will allow the above to happen. Most people, even many so-called 'experts', have no idea what is going on the background of the computers running an MS OS. But when you address that point to them, they gladly smile and retort, "That is what makes it so nice to work with, I do not have to know about that stuff."
Scary.
