On the other end of the spectrum, I'm a PC gamer and I haven't bought any VR equipment because there are way too many games to play as it is. I don't feel the need to increase the backlog of games I want to play if I won't realistically be able to play them.

If you are into simulations (driving, flying) then I'd say get a headset ASAP. Also potentially if you see yourself getting into immersive rhythm/fitness games. Otherwise I think it's pretty reasonable to wait for more compelling content to be released (and reap the benefits of the better hardware that will be available at that time).
