I dunno, I'm going to keep upgrading my Windows box and version so long as it stays the primary gaming platform. Consoles are fine and all, I even have a couple modern ones, but there's still no replacement for mouse & keyboard for hi-fidelity input, and the only desktop that lets you play the vast majority of m&k games is Windows.

That'll keep it in the home, and AD & Office will keep it in the workplace. Seems not so doomed to me.
