In my honest opinion is that it is the perfect time to give up on them. The design has gone down hill, and frankly the usefulness too. Vista was the top of the hill. 7 is a little down it, and 8 farther. If they make it to 9, it will likely be as bad or worse than vista-8 anyway.
I stand by my statement. I will not use anything farther than 7. Once games stop working on 7 (likely DX12), then I will just not use games anymore. Windows will be forever gone to me then. Going away from the dark ages that will be.
