I'm late weighing in on this I suppose, but I just wanted to offer my point of view.
I don't touch Facebook, or Yahoo, Twitter, Paypal, most banks, or any other "service" like that, but in some cases with hardware I make exceptions.
I own an iPhone 4S. It is an excellent device. I do not agree with many of Apple's business practices, nor Sprint, and I do not pay a monthly service for cellular connection. However, I purchased this device because I knew I could jailbreak it and full control over the hardware. Thus, despite what I consider unfriendly intentions, the device I purchased truly became mine, and I was satisfied with my purchase.
I will buy an Occulus Rift, and this Facebook deal doesn't even give me a momentary pause in that decision. It would be a harder decision if it had a big Facebook logo added, but I am no stranger to repainting plastic shells. This is a display device, not an OS. I think many hardware manufacturers should make friendlier business decisions, but I choose to buy hardware. While I much prefer companies such as Dragonbox.de to those others, Occulus Rift is far enough ahead of the competition that I will be buying one.
Occulus Rift + Pyra = a portable virtual universe. Technology is wonderful! How amazing would a 3D Occulus Rift based Desktop Environment be? Or just the Occulus version of XBMC!
Where's the button to skip ahead to the point where I receive these devices?
