Pros
Pro Controller-free 3D tracking
With 2 cameras on front of the unit, the Sulon Q can produce a 3D map of the room you're in without the need for stationary sensors to track your movement. This also means that it can track the position of your hands, meaning there will be no need to hold onto controllers.
Pro AR as well as VR
Virtual reality is available, however this headset also supports augmented reality. This bridges virtual reality with the real world, allowing VR components to overlap in the real world.
You can see an example of the Augmented reality in the Magic Beans Demo video.
Pro Wear and play
The Sulon Q can be used completely un-tethered. That means no cables to drag around, and no need to worry about upgrading your PC to be VR-ready. It incorporates PC components right into the headset - 256GB SSD, 8GB RAM, AMD FX-8800P process and a Radeon R7 graphics card. It also includes a 2560x1440p OLED display to complete the build.
These components are housed in the box that rests on the back of the wearer's head, and helps balance out the weight of the headset.
Pro Great displays
There are two OLED displays with a total resolution of 2560x1440 - beating out the Oculus Rift and HTC Vive slightly. The Sulon Q's displays can manage a 90Hz refresh rate which is said to reduce motion-nausea significantly.
Pro Can be used cordless
The device has battery life of up to 7 hours of use cord free. This is great for those that do not wish to be tethered to any objects.
Pro Plenty of content streams
Content will be available from a wide range of providers, including: Android/Google Cardboard, Gameface, Steam VR, Lighthouse.
Cons
Con Likely expensive
Because all of the components are integrated into the unit (GPU, CPU, battery), this will raise the cost instead of offloading the processing to a dedicated computer.
Con Console quality
While its not definitive what "console quality" specifically means, don't expect insane framerates. With the on-board GPU and battery, there's only going to be so much performance available.
Con Likely very heavy
Because it's un-tethered, it needs the CPU, GPU, as well as a hefty battery installed on the unit. The final weight isn't known yet, but it's likely going to be quite heavy.
Con Bulky
The EP1 is blocky and heavy at 445g, thanks to it's included Tegra X1 SoC and cooling solution.
Con May be noisy with moving parts
The device has a built in smartphone chip that will need cooling in order to run Android games natively. This fan will cause some noise as well as moving air (from the top of the unit), which all may be a bit distracting.
