Comment from FOVE Support:
Yes, as stated in the tech requirements on our website, we unfortunately don't support Windows 7 yet.
We are working on a beta for Windows 7, and we might be announcing it to a small group on our community at support.getfove.com. If you keep an eye on the forums, you'll hear when we launch the beta.
The initial tech specs did say "Windows" and changed at some point to Win 8.1 or 10. The blowback from Win7 users was enough to get them to run a special Beta for Win7. This change was noted in one of their update emails, but I never saw it.
[HJ]-RedRaven - The cables are lighter than the Vive, about eight feet long and tied with Velcro straps every 12-15". While lighter than the Vive cables, I wouldn't call them flimsy. I would say they were adequate for the task.
Got a friend with a Win10 box?
