That's the 128gb model the 64gb model is 450 at Coolblue. No real need for the bigger model as the games are way smaller on the Quest. You can put appr 45 on the 64gb, unless you are planning on downloading thousands of custum Beat saber songs ofc. I returned the big one once I found out about that and spent the money on accessories.

Cosmos are all rumors but the rumors are very promising. Inside out tracking is confirmed so no fiddling around with base stations. If the rumors are true is will be a wireless headset powered by your pc if you are within a 100 feet of your pc with pc quality graphics. When you are further away it will be a portable device just like the Quest with also lowered graphics. It will be definitely better than the Vive pro as that is not so good at all, quite bad actually. It will be way more expensive for sure and sofar I am blown away by the quality of the Quest. I read the reviews too and I think they were written by people that did not try it. I get motion sick very fast but the 72Hz doesn't make any difference at all. You can not even see or feel the difference with 90hz. If you have a very small bedroom I think you NEED a Quest as that you can take to any nearby parking garage having a huge play area :). Think about it!

Ofc there will be better headsets in the future and within a few years I think they will all be wireless but I can't wait forever I want to enjoy it now. And it being all in one is so convenient. I was expecting to use my old pc headset for the more quite experiences and simple Quest for the active ones. But I didn't use my old headset once in the last few weeks. That makes me wonder if I will ever buy the Cosmos as that would mean starting up a pc etc. This putting up a baseball cap and go. Did not expect that to make such a difference but it does.
