The screens sound like a limitation of Windows, I don't think Linux will mind. About the desk, I don't see why you can't plug this in a laptop, apart from the fact that laptop GPUs aren't powerful enough yet.
Oculus is Windows-only from now until the foreseeable future.
And I guess I was being pedantic about the desk but you understand my point.
He said on reddit that all you need to to is plug in cables or DVI-to-HDMI adapters to "fake out" your graphics card thinking monitors are attached, but physical monitors are not required.
>The latest version (0.9.5) now supports multiple monitors as long as they are connected to the same GPU as the Rift. i'm working on adding support for multi-GPU and Optimus configurations. Multi-Monitor is only available in curved mode at the moment but I'll add support for flat mode at some point too.
You also need a computer to run the Rift. So unless you're cool looking like this (http://i.imgur.com/1HMnJoc.jpg) then you'll need a desk to put that on.
