The flow is an ultra portable (think ultra light HMD that uses glasses arms to support itself on your head), phone controlled (Accelerometer and screen swiping) and phone driven (as in uses the phone video graphics) device which is a 3DOF headset primarily aimed at content consumption rather than games. Unfortunately at its price point, and lacking the controller and movement I'm use to with my headsets, it's a non starter for me. It's an interesting idea at half its price, maybe. Facebook gaining control of mass VR is basically why I feel pretty bearish about VR in general. If there's any company that can turn it into an anti consumer ad driven experience that experiments on you, its facebook. Hopefully valve continues to put out competing hardware even if its niche for people willing to pay for a premium experience. The main issue right now is, as you say video card availability and prices.
