It allows rendering only the parts the user is focused on in high quality and lower the resource usage of the device considerably.

Pros
Pro Comfortable to wear
The headset is lightweight at just 246g, and can be worn with glasses. It will automatically adjust depending on your pupil distance, and has a low latency at 13ms to help reduce motion-sickness.
Pro Low system requirements required
To run, you only need an Intel i3-540 CPU, nVidia GTX 660 GPU, and 4GB of RAM.
For a better experience, it's suggested you have at least Intel i5-4590 CPU and nVidia GTX980 GPU and 8GB of RAM.
Pro Convenient touch panel
There is a touch panel with a power and menu button built into the side of the device. While there are no menus in the headset itself, games could take advantage of this touchpad, which could be convenient.
Pro Plans to have foveated rendering
Foveated rendering is a rendering method where the quality of the image (and subsequently the processing power needed to render the image) throughout the image is different. It allows rendering only the parts the user is focused on in high quality and lower the resource usage of the device considerably.
Pro Supports eye tracking
The device has a built in eye tracking function that is supposed to help with things like targeting, much like eye targeting used in fighter jets.
Pro Able to access lots of content
Originally only Unity, Unreal Engine, and Cryengine were supported, but support for OpenVR and Steam VR are in the works. This will ensure there is plenty of content available for the Fove.
Pro Crisp graphics
The picture is meant to be clear due to the quad HD (2560x1140) display. This high resolution will help text and edges of round objects look crisp.
Cons
Con Poor early implamentation
The sensors tend to overcompensate for your movement, which results in motion sickness, and also early demos have had very unstable software. There's time to tweak these before the full launch, but are present as of now.
Con Padding is not adjustable
While the device is wide enough for a normal pair of glasses, the padding is not adjustable meaning those with larger heads or wide set glasses may have trouble.
Con Fove's eye-tracking technology is terrible.
It is hard to apply to the game, and it is very inaccurate.
Con Currently eye tracking has to be calibrated at the start of every game
The built in eye tracking currently has to be recalibrated every time a new demo/game is started. This can be time consuming and interrupts the flow of play for those that like to try out many different games in one session.
Con Highly demanding specs
The recommended specs for this device is a PC that can run modern games at 2560x1440 at 100fps or greater. This means the one will need a very high powered GPU CPU combo.
