I sincerely don't miss the lighthouses and cables, and can make a new area in any part of the house, at any time.
I just wish it wasn't owned by Facebook. But there's no competitor, unfortunately.
Cosmos also has inside out tracking so no beacons and I honestly don't mind the cables. I never really notice them when I play. I did with the original Vive when I tried it at work, though. As for the PC, I'm an avid gamer and graphics programmer for a AAA studio. My VR is set up in my home office so I have access to a more than adequate PC, anyway.
What I really do mind is a lack of graphical fidelity. Cosmos was the first option I tried which really felt good enough for me (the original Vive always felt cool but not quite there) and I know Quest has very similar resolution. But noticeable compression artifacts sound like something that would really bother me.
I'm very happy with my Vive Cosmos and it works without a Facebook account and hasn't shown me any ads so far.
