@Daniel... At some point doesn't it become a cost issue for MS? They have to spend $$$ to support their OS's. How long do you keep an OS active? What MS is doing is nothing new. I think most software companies end support for older versions at some point. I think the big mistake MS made is with Vista. That was the one after XP and the reason people didn't jump off of XP, for good reason. Vista was terrible with its use of memory. I think that still is hurting them.
